In this work, we propose Implosion Fabrication (ImpFab) as a versatile nanophotonics fabrication platform providing the highest spatial resolution, material versatility, and full volumetric control. ImpFab uniquely combines top-down lithography with bottom-up nanoparticle assembly within a hydrogel scaffold, enabling precise control over optical material properties, such as refractive index, by adjusting printing parameters. We showcase the potential of ImpFab by fabricating three-dimensional photonic crystals and quasicrystals, as well as demonstrating optical structures with spatially modulated unit cell material properties. Our results highlight the potential of ImpFab in producing nanostructures with tailored optical functionalities, which are crucial for applications in sensing, imaging, and information processing, and opening new avenues in developing non-Hermitian photonic systems with spatially controlled gain and loss. article_number: '145' article_processing_charge: No article_type: original author: - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin - first_name: Gaojie full_name: Yang, Gaojie last_name: Yang - first_name: Brian full_name: Mills, Brian last_name: Mills - first_name: André full_name: Grossi Fonseca, André last_name: Grossi Fonseca - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Quansan full_name: Yang, Quansan last_name: Yang - first_name: Justin full_name: Beroz, Justin last_name: Beroz - first_name: Steven E. full_name: Kooi, Steven E. last_name: Kooi - first_name: Marc full_name: de Miguel Comella, Marc last_name: de Miguel Comella - first_name: Kiran full_name: Mak, Kiran last_name: Mak - first_name: Sachin full_name: Vaidya, Sachin last_name: Vaidya - first_name: Daniel full_name: Oran, Daniel last_name: Oran - first_name: Corban full_name: Swain, Corban last_name: Swain - first_name: Yi full_name: Sun, Yi last_name: Sun - first_name: Shai full_name: Maayani, Shai last_name: Maayani - first_name: Jamison full_name: Sloan, Jamison last_name: Sloan - first_name: Amel full_name: Amin Elfadil Elawad, Amel last_name: Amin Elfadil Elawad - first_name: Josue J. full_name: Lopez, Josue J. last_name: Lopez - first_name: Edward S. full_name: Boyden, Edward S. last_name: Boyden - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić citation: ama: 'Salamin Y, Yang G, Mills B, et al.

We propose a method of creating spin-polarized electrons on an integrated photonics chip by laser-driven nanophotonic fields. A two-stage interaction separated by a free-space drift length is proposed, where the first stage and drift length introduces spin-dependent characteristics into the probability distribution of the electron wave function. The second stage uses an adjusted optical near field to rotate the spin states utilizing the spin-dependent wave-packet distribution to produce electrons with high ensemble average spin expectation values. This platform provides an integrated and compact method to generate spin-polarized electrons, implementable with millimeter scale chips and tabletop lasers. article_number: '063802' article_processing_charge: No article_type: original author: - first_name: Clarisse full_name: Woodahl, Clarisse last_name: Woodahl - first_name: Melanie full_name: Murillo, Melanie last_name: Murillo - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Aviv full_name: Karnieli, Aviv last_name: Karnieli - first_name: David A. B. full_name: Miller, David A. B. last_name: Miller - first_name: Olav full_name: Solgaard, Olav last_name: Solgaard citation: ama: Woodahl C, Murillo M, Roques-Carmes C, Karnieli A, Miller DAB, Solgaard O.

By engineering supercollimation, which is light propagation without angular spreading, within the emission spectrum, we strongly shape the angular emission profile of the scintillator, dramatically reducing blurring at large thicknesses. Our theoretical and numerical results, using realistic scintillator and photonic crystal parameters, show that this improves the Detector Quantum Efficiency (DQE) by up to several orders of magnitude at high spatial frequencies, enabling sharper images and reduced X-ray dosages.

The presence of non-Hermiticity leads to many topological physics phenomena and device applications. In the non-Hermitian energy band theory, the foundation of these physics and applications, both energies and wave vectors take complex values. The energy bands thus become a Riemann surface, and such an energy-band Riemann surface underlies all important signatures of non-Hermitian topology. Despite a long history and recent theoretical interests, the energy-band Riemann surface has not been experimentally studied. Here, we provide a photonic observation of the energy-band Riemann surface of a non-Hermitian system. This is achieved by a tunable imaginary gauge transformation in photonic synthetic frequency dimensions. From measured topologies of the Riemann surface, we reveal the complex-energy winding, the open-boundary-condition spectrum, the generalized Brillouin zone, and the branch points. Our findings demonstrate a unified framework in the studies of diverse effects in non-Hermitian topological physics through an experimental observation of energy-band Riemann surfaces. article_number: eaec8239 article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Dali full_name: Cheng, Dali last_name: Cheng - first_name: Heming full_name: Wang, Heming last_name: Wang - first_name: Janet full_name: Zhong, Janet last_name: Zhong - first_name: Eran full_name: Lustig, Eran last_name: Lustig - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Shanhui full_name: Fan, Shanhui last_name: Fan citation: ama: Cheng D, Wang H, Zhong J, Lustig E, Roques-Carmes C, Fan S.

This expands the quantum optics toolbox to incorporate free-electron beams for applications in highly tunable quantum control, imaging, and spectroscopy at the nanoscale. The framework recovers previously studied results and shows that electromagnetic environments can amplify the intrinsically weak coupling between a free-electron and a bound electron to reach previously inaccessible interaction regimes. We leverage this enhanced coupling for experimentally feasible protocols in coherent qubit control and towards the nondestructive readout and projective control of the electron beam's quantum-number statistics. Our framework is broadly applicable to microwave-frequency qubits, optical nanophotonics, cavity quantum electrodynamics, and emerging platforms at the interface of electron microscopy and quantum information. article_number: '2601.21385' article_processing_charge: No arxiv: 1 author: - first_name: Jakob M. full_name: Grzesik, Jakob M. last_name: Grzesik - first_name: Aviv full_name: Karnieli, Aviv last_name: Karnieli - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Dylan S. full_name: Black, Dylan S. last_name: Black - first_name: Trung Kiên full_name: Lê, Trung Kiên last_name: Lê - first_name: Olav full_name: Solgaard, Olav last_name: Solgaard - first_name: Shanhui full_name: Fan, Shanhui last_name: Fan - first_name: Jelena full_name: Vučković, Jelena last_name: Vučković citation: ama: Grzesik JM, Karnieli A, Roques-Carmes C, et al.

We present a photonic integrated circuit that enables the generation and analysis of arbitrary polarization states. The device provides reconfigurable access to the full polarization degree of freedom of coherent light within a single integrated platform. We experimentally demonstrate arbitrary polarization state generation spanning the Poincare sphere, as well as Stokes vector measurement on chip. Unlike conventional Stokes measurements that rely on direct detection, polarization analysis utilizing this architecture is intrinsically non-destructive, preserving the optical signal for further optical domain processing. The devices are fabricated in a commercial foundry using CMOS-compatible processes, enabling scalable and reproducible integration. By combining polarization generation and analysis in a compact and stable photonic circuit, this work eliminates the need for external polarization optics and provides a foundation for robust, polarization-enabled photonic integrated systems. article_number: '2602.17024' article_processing_charge: No arxiv: 1 author: - first_name: Carson G. full_name: Valdez, Carson G. last_name: Valdez - first_name: Anne R. full_name: Kroo, Anne R. last_name: Kroo - first_name: Anna J. full_name: Miller, Anna J. last_name: Miller - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: David A.

Topological physics in three or more dimensions exhibits rich phenomena without lower-dimensional counterparts. In this paper, the authors propose a scheme to implement such high-dimensional topological physics in a single photonic ring resonator, where the model of interest can be arbitrarily high dimensional and arbitrarily multi-band. The frequency modes in the resonator, coupled via electro-optic modulation, are used to create a high-dimensional lattice, and the spatial modes are used as the pseudo-spin degree of freedom within each lattice site. The band structure of the model can be measured from the transmission spectrum of the ring resonator. The authors numerically demonstrate as examples a three-dimensional, two-band model and a five-dimensional, four-band model. This paper establishes a versatile and programmable platform for high-dimensional topological physics, paving the way for its experimental studies and future applications. article_number: '100163' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Dali full_name: Cheng, Dali last_name: Cheng - first_name: Heming full_name: Wang, Heming last_name: Wang - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Janet full_name: Zhong, Janet last_name: Zhong - first_name: Shanhui full_name: Fan, Shanhui last_name: Fan citation: ama: Cheng D, Wang H, Roques-Carmes C, Zhong J, Fan S.

This trade-off is particularly pronounced in polymer scintillators, which, despite their fast emission, exhibit low density and low atomic numbers, limiting the radiation attenuation factor, resulting in low detection efficiency. Here, we overcome this limitation by creating a heterostructure scintillator of alternating nanometric layers, combining fast light-emitting polymer scintillator layers and transparent stopping layers with a high radiation attenuation factor. The nanolayer thicknesses are tuned to optimize the penetration depth of recoil electrons in active emissive layers, maximizing the conversion of X-rays to visible light. This design increases light output by up to 1.5 times and enhances imaging resolution by a factor of 2 compared to homogeneous polymer scintillators due to the ability to use thinner samples. These results demonstrate the potential of heterostructure scintillators as next-generation detector materials, overcoming the limitations of homogeneous scintillators. article_processing_charge: No article_type: letter_note author: - first_name: Orr full_name: Be’er, Orr last_name: Be’er - first_name: Avner full_name: Shultzman, Avner last_name: Shultzman - first_name: Rotem full_name: Strassberg, Rotem last_name: Strassberg - first_name: Georgy full_name: Dosovitskiy, Georgy last_name: Dosovitskiy - first_name: Noam full_name: Veber, Noam last_name: Veber - first_name: Roman full_name: Schuetz, Roman last_name: Schuetz - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Ido full_name: Kaminer, Ido last_name: Kaminer - first_name: Yehonadav full_name: Bekenstein, Yehonadav last_name: Bekenstein citation: ama: Be’er O, Shultzman A, Strassberg R, et al.

Therefore, thermal management is a critical barrier to the development of more powerful X-ray tubes with higher brightness and spatial coherence, which are needed to translate imaging modalities such as phase-contrast imaging to the clinic. In rotating anode X-ray tubes, the most common design, thermal radiation is a bottleneck that prevents efficient cooling of the anode─the hottest part of the device by far. We predict that nanophotonic patterning of the anode of an X-ray tube enhances heat dissipation via thermal radiation, enabling it to operate at higher powers without an increase in temperature. The focal spot size, which is related to the spatial coherence of generated X-rays, can also be reduced at a constant temperature. A major advantage of our “nanophotonic thermal management” approach is that in principle, it allows complete control over the spectrum and direction of thermal radiation, which can lead to optimal thermal routing and improved performance. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Simo full_name: Pajovic, Simo last_name: Pajovic - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Seou full_name: Choi, Seou last_name: Choi - first_name: Steven E. full_name: Kooi, Steven E. last_name: Kooi - first_name: Rajiv full_name: Gupta, Rajiv last_name: Gupta - first_name: Michael E. full_name: Zalis, Michael E. last_name: Zalis - first_name: Ivan full_name: Čelanović, Ivan last_name: Čelanović - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić citation: ama: Pajovic S, Roques-Carmes C, Choi S, et al.

Concurrently, computational imaging leverages algorithms to reconstruct images from optically processed signals, overcoming the limitations of traditional imaging systems. This Perspective explores the synergistic integration of metaoptics and computational imaging, “metaoptic computational imaging”, which combines the physical wavefront shaping ability of metasurfaces with advanced computational algorithms to enhance imaging performance beyond conventional limits. We discuss how metaoptic computational imaging addresses the inherent limitations of single-layer metasurfaces in achieving multifunctionality without compromising efficiency. By treating metasurfaces as physical preconditioners and codesigning them with reconstruction algorithms through end-to-end (inverse) design, it is possible to jointly optimize the optical hardware and computational software. Advanced applications and new frontiers in the field enabled by metaoptic computational imaging are highlighted, including phase imaging and quantum state measurement. article_processing_charge: No article_type: original author: - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Kai full_name: Wang, Kai last_name: Wang - first_name: Yuanmu full_name: Yang, Yuanmu last_name: Yang - first_name: Arka full_name: Majumdar, Arka last_name: Majumdar - first_name: Zin full_name: Lin, Zin last_name: Lin citation: ama: Roques-Carmes C, Wang K, Yang Y, Majumdar A, Lin Z.

In coupled systems of light and matter, entanglement manifests itself in the linear superposition of multipartite quantum states (e.g., parametrized by the multiple spatial, spectral, or temporal degrees of freedom of a light field). In bipartite systems, the Schmidt decomposition provides a modal decomposition of the entanglement structure over independent, separable states. Although ubiquitous as a mathematical tool to describe and measure entanglement, there exists no general efficient experimental method to decompose a bipartite quantum state onto its Schmidt modes. Here, we propose a method that relies on bipartite self-configuring optics that automatically ``learns'''' the Schmidt decomposition of an arbitrary pure quantum state. Our method is agnostic to the degrees of freedom over which quantum entanglement is distributed and can reconstruct the Schmidt modes and values by variational optimization of the network''s output powers or coincidences. We illustrate our method with numerical examples of spectral entanglement analysis for biphotons generated via spontaneous parametric down conversion and provide experimental guidelines for its realization, including the influence of losses and impurities. Our method provides a versatile and scalable way of analyzing entanglement in bipartite integrated quantum photonic systems.

Recent advances in the artificial structuring of scintillators offer new opportunities for improving the energy resolution of scintillator-based X-ray detectors. Here, we present a three-bin energy-resolved X-ray imaging framework based on a three-layer multicolor scintillator used in conjunction with a physics-aware image postprocessing algorithm. The multicolor scintillator is able to preserve X-ray energy information through the combination of emission wavelength multiplexing and energy-dependent isolation of X-ray absorption in specific layers. The dominant emission color and the radius of the spot measured by the detector are used to infer the incident X-ray energy based on prior knowledge of the energy-dependent absorption profiles of the scintillator stack. Through ab initio Monte Carlo simulations, we show that our approach can achieve an energy reconstruction accuracy of 49.7%, which is only 2% below the maximum accuracy achievable with realistic scintillators. We apply our framework to medical phantom imaging simulations where we demonstrate that it can effectively differentiate iodine and gadolinium-based contrast agents from bone, muscle, and soft tissue. article_number: '158' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Seokhwan full_name: Min, Seokhwan last_name: Min - first_name: Seou full_name: Choi, Seou last_name: Choi - first_name: Simo full_name: Pajovic, Simo last_name: Pajovic - first_name: Sachin full_name: Vaidya, Sachin last_name: Vaidya - first_name: Nicholas full_name: Rivera, Nicholas last_name: Rivera - first_name: Shanhui full_name: Fan, Shanhui last_name: Fan - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes citation: ama: 'Min S, Choi S, Pajovic S, et al.

Their widespread use relies on scalable, high-quality manufacturing methods. Nanophotonic scintillators, featuring wavelength-scale nanostructures, can offer improved emission properties such as higher light yield, shorter decay times, and enhanced directionality. However, achieving scalable fabrication of these structures remains challenging. Here, we present a scalable fabrication method for large-area nanophotonic scintillators based on the self-assembly of chalcogenide glass photonic crystals. This technique enables the production of nanophotonic scintillators over wafer-scale areas, achieving a six-fold enhancement in light yield compared to unpatterned scintillators. By studying surface nanofabrication disorder, we show its impact on imaging performance and provide a route towards scintillation enhancements without compromising resolution. We demonstrate the practical applicability of our nanophotonic scintillators through X-ray imaging of biological and inorganic specimens. Our results could enable the industrial implementation of a new generation of nanophotonic-enhanced scintillators. article_number: '5750' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Louis full_name: Martin-Monier, Louis last_name: Martin-Monier - first_name: Simo full_name: Pajovic, Simo last_name: Pajovic - first_name: Muluneh G. full_name: Abebe, Muluneh G. last_name: Abebe - first_name: Joshua full_name: Chen, Joshua last_name: Chen - first_name: Sachin full_name: Vaidya, Sachin last_name: Vaidya - first_name: Seokhwan full_name: Min, Seokhwan last_name: Min - first_name: Seou full_name: Choi, Seou last_name: Choi - first_name: Steven E. full_name: Kooi, Steven E. last_name: Kooi - first_name: Bjorn full_name: Maes, Bjorn last_name: Maes - first_name: Juejun full_name: Hu, Juejun last_name: Hu - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes citation: ama: Martin-Monier L, Pajovic S, Abebe MG, et al.

However, the intrinsic weakness of optical nonlinearity and reciprocity of nonlinear interactions generally places stringent limits on the efficiency of nonlinear optical processes and their ability to be tailored for advanced applications in multimode systems. Here, motivated by recent advances in using non-Hermitian photonics and gain/loss engineering to enable non-reciprocal light transport, we explore how the interplay between non-Hermiticity and optical nonlinearity leads to a fundamentally new regime of nonlinear frequency conversion. We show how non-Hermitian coupling between discrete frequency modes can result in non-reciprocal flow of energy in a frequency dimension, closely resembling the non-Hermitian skin effect (NHSE). Applying our theory to a multimode nonlinear cavity supporting cascaded nonlinear processes, we demonstrate chiral energy flow in a frequency dimension, leading to long-range frequency shifts of quasi-continuous wave sources, shaped frequency combs robust to defects and disorder, terahertz (THz) generation far exceeding the Manley-Rowe limit, and nonlinear multimodal limit cycles for multi-frequency pump-probe spectroscopy. article_number: '7544' article_processing_charge: No article_type: original author: - first_name: Sahil full_name: Pontula, Sahil last_name: Pontula - first_name: Sachin full_name: Vaidya, Sachin last_name: Vaidya - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Shiekh Zia full_name: Uddin, Shiekh Zia last_name: Uddin - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin citation: ama: Pontula S, Vaidya S, Roques-Carmes C, Uddin SZ, Soljačić M, Salamin Y.

Optical cavities are essential to generate and manipulate non-classical light. However, detecting changes in cavity properties induced by the quantum state remains a critical challenge in the optical domain due to the weak material nonlinearity. Here, we propose a framework for observing the dynamics of quantum states generated inside nonlinear optical cavities. We leverage the symmetry-breaking process of a bistable system, which is highly sensitive to the initial state, enabling detection of quantum state displacement through an asymmetric equilibrium of a macroscopic observable. With a nonlinear response at the single photon level, our approach directly imprints the cavity field distribution onto the statistics of bistable cavity steady-states. We experimentally demonstrate our approach in a degenerate optical parametric oscillator, generating and reconstructing different quantum states. As a validation, we reconstruct the Husimi Q function of the cavity squeezed vacuum state. In addition, we observe the evolution of the quantum vacuum state inside the cavity as it undergoes phase-sensitive amplification. By enabling generation and measurement of quantum states in a single nonlinear optical cavity, our method paves a way for studying exotic dynamics of quantum optical states in nonlinear driven-dissipative systems. article_number: '7576' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Seou full_name: Choi, Seou last_name: Choi - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Jamison full_name: Sloan, Jamison last_name: Sloan - first_name: Michael full_name: Horodynski, Michael last_name: Horodynski - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić citation: ama: Choi S, Salamin Y, Roques-Carmes C, Sloan J, Horodynski M, Soljačić M.

Taming this noise is pivotal to a wide range of applications, both classical and quantum. Here we demonstrate the creation of intense light with quantum levels of noise even when starting from inputs with large amounts of excess noise. In particular, we demonstrate how intense squeezed light with intensities approaching 0.1 TW cm−2, but noise at or below the shot-noise level, can be produced from noisy inputs associated with high-power amplified laser sources (an overall noise reduction of 30-fold). On the basis of a new theory of quantum noise in multimode systems, we show that the ability to generate quantum light from noisy inputs results from multimode quantum correlations, which maximally decouple the output light from the dominant noise channels in the input light. As an example, we demonstrate this effect for femtosecond pulses in nonlinear fibres, but the noise-immune correlations that enable our results are generic to many other nonlinear systems in optics and beyond. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Shiekh full_name: Zia Uddin, Shiekh last_name: Zia Uddin - first_name: Nicholas full_name: Rivera, Nicholas last_name: Rivera - first_name: Devin full_name: Seyler, Devin last_name: Seyler - first_name: Jamison full_name: Sloan, Jamison last_name: Sloan - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Shutao full_name: Xu, Shutao last_name: Xu - first_name: Michelle Y. full_name: Sander, Michelle Y. last_name: Sander - first_name: Ido full_name: Kaminer, Ido last_name: Kaminer - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić citation: ama: Zia Uddin S, Rivera N, Seyler D, et al.

We experimentally confirm\r\nthe presence of non-Abelian lattice gauge fields by two signatures: linear band\r\ncrossings at the Dirac cones, and the associated direction reversal of eigenstate\r\ntrajectories. We further demonstrate a non-Abelian scalar lattice gauge potential that\r\nlifts the degeneracies of the Dirac cones. Our results highlight the implications of\r\nnon-Abelian lattice gauge fields in topological physics, and provide a starting point\r\nfor demonstrations of emerging non-Abelian physics in the photonic synthetic\r\ndimensions.
