摘要

利用传递矩阵法从理论上研究了基于光子晶体tue - morse结构的光学滤波器的设计和特性。结果表明，通过在原结构中引入缺陷层，改变了该滤波器的主要特性。tue - morse结构的这一缺陷的主要优点是它能够适用于DWDM通信。换句话说，通过tue - morse光子晶体结构实现DWDM滤波器要容易得多。通过改变缺陷参数可以获得所需的波长。该滤波器的优点之一是效率高。该结构的传动效率约为96%，质量因数大于77000。

Important Effect of Defect Parameters on the Characteristics of Thue-Morse Photonic Crystal Filters

Design and characterization of optical filters based on photonic crystal Thue-Morse structures are theoretically examined using transfer matrix method. It is shown that by introducing defect layer in the original structure of the proposed filter, main characteristics of it are changed. The main advantage of this defect in Thue-Morse structure is its capability for DWDM communication applications. In other words, achievement of DWDM filter through the Thue-Morse photonic crystal structure is much easier. The desired wavelengths can be achieved by changing the defect parameter. High efficiency of the proposed filter is one of its benefits. The transmission efficiency of this structure is about 96% and the quality factor is more than 77000.
