Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control
Advanced Optical Materials, EarlyView.This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.
