Theoretical study of reflective phase compensator made of photonic crystal

In order to make new optical devices with photonic crystal,three reflective phase compensators made of 1-D photonic crystals are investigated with transfer matrix method and numerical value calculation.Three different compensators are discussed respectively by means of both parameters of reflective amplitude coefficient ratio.The results show that these reflective phase compensators own some advantages of high-reflectivity,continuous tunable phase compensation etc.
