摘要: 采用传输矩阵法通过数值计算模拟的方式,研究缺陷对一维光子晶体滤波性能的调制作用,结果表明:当含缺陷单元位于光子晶体周期性排列结构中间时,缺陷数目可改变光子晶体的滤波通道（缺陷模）数目和滤波品质,但不改变透射率;当含缺陷单元偏离光子晶体结构中心越远,光子晶体各滤波通道的透射率就越低,但滤波通道之间的距离保持不变;随着两个含缺陷的单元之间距离增大,光子晶体各滤波通道的滤波品质升高并出现简并趋势;当缺陷的厚度成倍数增大时,各滤波通道滤波品质升高并出现多系多通道滤波现象。缺陷对一维光子晶体滤波特性的影响规律,为光子晶体设计新型光学滤波器件及其调制机制提供理论参考。

Abstract: The modulation effect of defect on the filter properties of one-dimensional photonic crystal was studied by transfer matrix theory and numerical simulation method. The result shows that when the defect unit is located in the center of the periodically arranged structure of photonic crystal, defect modes number and filtering quality are changed with the number of defect, but the transmittance remains the same; with the increasing deviation of defect unit from the photonic crystal center, the transmittance of each filter channel in photonic crystal will be lower, but the distance between the filter channels is unchanged; the filtering quality of each filter channel is improving with the increasing distance between two defect units, and the defect modes are degenerating; when defect thickness multiply increases, filtering quality of each channel is improving and multi-channel filtering appears. Effect of defect on filter properties of one-dimensional photonic crystal can provide theoretical guidance and modulation mechanism to design high quality optical filters and optical switches
