Simultaneous polarization filtering and wavefront shaping enabled by localized polarization-selective interference

Abstract The ability of simultaneous polarization filter and wavefront shaping is very important for many applications, especially for polarization imaging. However, traditional methods rely on complex combinations of bulky optical components, which not only hinder the miniaturization and integratio...
