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

摘要：

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 splitting effect for the MWF structure,finding that it is in the angle range from 25 to 65 degree that the results are perfect. Outside this angle range, the results are unacceptable due to the rapid decay of TM mode power.
