摘　　要：为了提高硅基光子器件的集成度,文章设计了一种超紧凑微环谐振滤波器。根据光波导理论,推导出滤波器的传递函数,仿真得到滤波器的频谱特性。结果表明,微环半径为0.63μm,直波导宽度为0.25μm,环形波导宽度为0.3μm时,滤波器自由光谱范围为170 nm,插入损耗为1.5 dB,半峰全宽为5 nm,上述性能完全满足波分复用系统对滤波器的要求。In order to improve the integration of silicon-based photonic devices,an ultra-compact filter based on microring resonator was designed.According to the theory of optical waveguide,the transfer function of the filter was deduced and the spectrum characteristic were simulated numerically.The results show that when the the radius of resonator is 0.63μm,the width of the direct waveguide is 0.25μm,the width of the annular waveguide is 0.3μm,the filter with full wave at half maximum of 5 nm can be achieved,which also has an exceeding free spectral rang 170 nm and an insertion loss less of 1.5 dB.The performance can fully meet the requirements of the filter in the wavelength division multiplexing system.
