Herein, we offer a numerical study on the devising of unique 2D-heterostructure photonic crystal (PC) that can split two orthogonally polarized light waves. The analysis is performed via two-dimensional finite element method (2D-FEM) by utilizing COMSOL Multiphysics software. device consists discrete designs PC formation. first formation optimized so it permits both TE- and TM-polarization to t...
