Metasurface enabled broadband, high numerical aperture Laplace differentiator under multiple polarization illumination

Abstract Optical metasurfaces to perform optical analog spatial differentiation operations and image edge detection processing is a currently hot topic. However, some metasurface differentiators are limited by polarization dependence, narrow operating bandwidth, low numerical aperture (NA), requirin...
