摘　　要：利用光子晶体的光子禁带和光子局域的两点特性,对一维光子晶体带隙和加入缺陷后光子禁带中出现极窄透射带宽进行了分析,设计了中心波长在532 nm、透射谱线宽度低至0.0002 nm,中心波长透射率接近100%,带外透射率为0%的一维光子晶体滤波器,并对一维光子晶体滤波器的滤波特性进行仿真。结果得出:在入射角偏移时,透射峰中心波长向短波方向偏移,峰值透射率有所下降,运用缺陷层厚度变化可导致透射峰偏移的特性,对入射角引起的透射峰偏移进行修正。In light of the characteristics of photonic band gap and the localization of photon, the photonic band gap and the bandwidth are analyzed and simulated when the defeat is joined. Then a one-dimensional photonic crystal filter with central wavelength 532 am, bandwidth as low as 0.0002 nm, the center wavelength transmission rate close to 100 percent, and on both sides the center wavelength transmission rate of 0, is designed. When the incident angle is offset, the transmission peak wavelength shifted to shorter wavelength, the peak transmission rate decreased to some extent, the characteristic that the shift of the transmission peaks changes as the thickness of the defect layer changes is applied to modify the shift of the transmission peaks changed with the angle of incidence.
