SiGe-OI微环谐振器的滤波特性分析
Analysis of the filtering property of SiGe-OI micro-ring resonator
摘要
Abstract
SiGe-OI micro-ring resonator is a new type of resonator with semiconductor material.In this paper,according to the transfer function of micro-ring resonator by the transfer matrix method,the typi-cal curve of the intensity transfer function of the drop channel and main channel are researched.The fil-tering property of SiGe-OI micro-ring resonator is analyzed with the filtering property influenced by cou-pling coefficient.The model of SiGe-OI micro-ring resonator is built by the simulation software,with the structure parameters,coupling coefficient,3 dB bandwidth and extinction ratio being mainly analyzed. The relationships between wave guide width,coupling gap,wavelength and coupling coefficient are sim-ulated,and the influences of 3 dB bandwidth and extinction ratio are analyzed from the coupling coeffi-cient.Finally,the range of coupling coefficient is accessed,and the filtering property is obtained in the condition of different coupling coefficients,providing a theoretical reference for research on SiGe-OI mi-cro-ring resonator.关键词
