Adjustable and robust methods for polarization-dependent focusing Schmid, David Huang, Ting-Yu Hazrat, Shiraz Dirks, Radhika Onur Hosten ; https://orcid.org/0000-0002-2031-204X Quint, Stephan Thian, Dickson Kwiat, Paul G We present two methods for the precise independent focusing of orthogonal linear polarizations of light at arbitrary relative locations. Our first scheme uses a displaced lens in a polarization Sagnac interferometer to provide adjustable longitudinal and lateral focal displacements via simple geometry; the second uses uniaxial crystals to achieve the same effect in a compact collinear setup. We develop the theoretical applications and limitations of our schemes, and provide experimental confirmation of our calculations.
