摘要：自从1987年Yablonovitch和John开创性地提出光子晶体这一新概念以来，光子晶体的结构、制备和量子电动力学特性研究开始备受人们关注并得到广泛的研究。而光子晶体最显著的特点就是对某些频率的电磁波的抑制作用，产生出光子禁带。这一特性最直接的应用便是实现对光子的极优良的滤波性能。本文主要利用时域有限差分方法，设计了一个六通道的光子晶体滤波器，并研究了这一滤波器的性质。

Abstract：In 1987 Yablonovitch and John proposed a new concept of photonic crystal. Since then, the structure, fabrication and quantum electrodynamics of photonic crystal have attracted much attention and been studied extensively. The most remarkable property of photonic crystal is the inhibition of certain frequencies of electromagnetic waves and the formation of forbidden band of photons. This most direct application of the characteristic is the realization optical filters of great performance. This paper mainly designs a six channel photonic crystal filter, and studies its properties using finite-difference time-domain method.

Key words: photonic crystal; FDTD method; multi-channel optical filter
