  bibo_abstract:
  - Bio-inspired photonic synapses integrate optical sensing, memory, and processing
    in a single platform, overcoming the bottlenecks of traditional CMOS-based vision
    sensors. Most existing neuromorphic vision systems either rely on electrical inputs
    for bidirectional conductance modulation, limiting their operating speed and bandwidth,
    or lack nonvolatility, leading to nonlinear weight updates and poor efficiency
    in image recognition tasks. Here, we report a two-terminal, fully light-controlled
    synaptic memristor based on CsPbBr3/ZnO nanorod heterojunction that demonstrates
    4-bit memory storage and optical logic operations within a single architecture.
    The device emulates essential functions of both excitatory and inhibitory synapses,
    utilizing positive photoconductivity under UV illumination (λ = 375 nm) and anomalous
    negative photoconductivity under visible light (λ = 450 nm). By controlling defect
    concentrations at the CsPbBr3/ZnO nanorod interface, the device exhibits nonvolatile
    multibit memory with near-linear, symmetric conductance modulation, achieving
    92.4% image recognition accuracy with a convolutional neural network. The bidirectional
    photoresponse enables reconfigurable optical logic operations, demonstrating integrated
    logic-in-memory. Additionally, when integrated on a flexible platform, the device
    demonstrates stable synaptic performance under repeated mechanical bending. These
    results highlight the potential of CsPbBr3/ZnO nanorod heterojunction-based all-photonic
    synapses as building blocks for multibit storage, optical information processing,
    and wearable neuromorphic vision systems.@eng
