Research on the Wide-Angle and Broadband 2D Photonic Crystal Polarization Splitter

Two novel wide-angle and broadband 2D photonic crystal polarization splitters (PCPS) which are the multilayer wavy films (MWF) structure and arrow-head like structure are designed based on the autocloning method. Plane wave expansion (PWE) method is used to calculate the band structure and explain t...

Description
Summary:Two novel wide-angle and broadband 2D photonic crystal polarization splitters (PCPS) which are the multilayer wavy films (MWF) structure and arrow-head like structure are designed based on the autocloning method. Plane wave expansion (PWE) method is used to calculate the band structure and explain the reason for the wide-angle and broadband polarization splitting effect. In order to verify the result derived from PWE method, finite-difference time-domain (FDTD) method is employed to test and measure the polarization effect for the MWF structure.
