Analysis of Transmission Characteristics of Micro-Ring Resonators Based on Photonic Crystal Structure

本文针对基于硅基光子晶体结构的双信道单环谐振器的传输特性进行了系统的模拟研究工作,分析中应用了有限时域有限差分法(FDTD)设计进行微环谐振器的建模和传输特性的分析。建立一种基于三角光子晶体结构的微环谐振器模型,并通过改变结构参数,构建不同的微环谐振器模型结构。同时,利用matlab软件对不同模型结构的微环谐振器仿真结果进行处理分析。其满足谐振条件的光波通过谐振器时,能够进行耦合,仿真得到的谐振器输出端的传输效率达到0.96,与理论分析结果基本相似。本文对理解基于光子晶体结构的微环谐振器的工作机制、传输特性分析以及自主设计有所帮助,并为其实际应用提供了理论分析基础。

According to the transmission characteristics of photonic crystal structure of the double channel single ring resonator based on simulated research, analysis in the application of the finite time domain finite difference method(FDTD) analysis modeling and transmission characteristics of micro-ring resonator design. The establishment of a micro ring resonator model based on triangular photonic crystal structure, and by changing the structure parameters, the construction of micro ring resonator different model structures. At the same time, the micro ring resonator simulation results of different model structures are processed and analyzed by using MATLAB software. In this paper, on the understanding of the working mechanism, micro ring resonator photonic crystal structure of transmission characteristics analysis and independent design based on help for its practical application, and provides a theoretical basis.
