有效抑制光子晶体加载矩形谐振腔中模式竞争的方法
An effective method for suppressing the mode competition in a rectangular cavity loaded with photonic crystals
摘要
Abstract
In this paper, the photonie crystal loaded rectangular resonant cavity is studied. Because the conventional way earmat ensure single-mode operation in the cavity when operated with higher-order modes, characteristic impedance method and perturbation method are employed to change the structure of the conventional photonic crystals cavity. The improved cavity that can work with a single higher-order mode is realized. On this basis, the conventional photonic crystal shielded cavity, which can work with a mode of TM_(530), is reformed by the new method. The new structures are analyzed by using analytical methods and HFSS. The physical reasons of these methods solving the problem of mode competition are also analyzed. The investigation reveals that the method can effectively suppress mode competition and realize single-modc operation in the cavity when operated with higher-order modes.关键词
