Reflective Phase Properties of two-dimensional Photonic Crystal within The Bandgaps Based on Surface Structures Regulation

摘要

Using the plane wave expansion method to determine the band gap of two dimensional photonic crystal, and then through the finite difference time domain method with relevant software and numerical calculation we study the influence of two-dimensional photonic crystal structure of photonic band gap on the reflective phase. The research results show that in the photonic band gap, reflectance is constant 1. We analyzed TM mode influence of the bandgap on the reflective phase and found that we can realize modulation of the reflective phase by surface structures regulation of two-dimensional photonic crystals.
