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 typical curve of the intensity transfer function of the drop channel and main channel are researched.The filtering property of SiGe-OI micro-ring resonator is analyzed with the filtering property influenced by coupling coefficient.The model of SiGe-OI micro-ring resonator is built by the simulation software,with the structure parameters,coupling coefficient,3dB bandwidth and extinction ratio being mainly analyzed.The relationships between wave guide width,coupling gap,wavelength and coupling coefficient are simulated,and the influences of 3dB bandwidth and extinction ratio are analyzed from the coupling coefficient.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 micro-ring resonator.
