The Improve of the Analyzing of 1-D photonic Crystal by Transfer Matrix Method

Photonic crystal is a new artificial complex media and the transfer matrix method is one of the most popular methods of analyzing the band-gap of one-dimension photonic crystal.Some improvements for this method are reported,such as adding multiple reflections and amending the phase items.In this paper,the authors propose a novel approach to compute the non-vertical incidence scenarios.The new method is validated through the measurement data.Moreover,the effects on the location and the width of the photonic band-gap caused by the ratio of refractive index,optical thickness and the number of cycle structure are also analyzed.AT last,the authors propose a methodology to improve one-dimensional photonic crystal behavior by choosing its thickness,number of periods,material property,and defects.
