Polarization-Independent Two-Layer Grating With Five-Port Splitting Output Under Normal Incidence

In this paper, we report a two-layer five-port diffraction grating by a polarization-independent design under normal incidence. To be different from conventional five-port gratings, initially, we design a novel two-layer grating with operation in transmission. Next, we firstly design a polarization-...
