一维变频光子晶体的透射特性

摘要

提出一种新的一维变频光子晶体,并给出其传输矩阵及电场分布表达式.在此基础上,计算一维变频光子晶体的透射率和电场分布,并研究变频函数、变频介质折射率、厚度、周期数及缺陷层对变频光子晶体透射率与电场分布的影响.结果表明,变频光子晶体比常规光子晶体的禁带更宽.%We proposed a new one-dimensional variable frequency photonic crystals (VFPCs ),and gave the expression of transmission matrix and electric field distribution.On this basis,we calculated transmissivity and the electric field distribution of one-dimensional VFPCs and studied the effect of variable frequency function,variable frequency medium refractive index,thickness,period numbers and defect layer on the transmissivity and the electric field distribution of the VFPCs.The results show that the photonic band gap of the VFPCs is wither than that of the conventional photonic crystals.
