设计了一个基于硅基微环的超紧凑的微波光子滤波器,用以提高硅基微波光子器件的集成密度及增大其自由光谱范围。根据波导光学的耦合模理论,推导出双环并联谐振器的光强传递函数,并通过仿真得到了微波光子滤波器的输出特性。结果表明:当微环半径为0.79μm时,谐振器中直波导宽度为0.3μm,环形波导宽度为0.25μm,滤波器的自由光谱范围为140 nm,插入损耗为0.5 dB,半峰全宽为7 nm,此滤波器的性能完全满足粗波分复用系统的要求。

The ultra-compact microwave photonic filter based on silicon-on-insulator microring resonator was designed to increase the integration density of microwave photonic devices and enlarge the free spectral range. According to the coupled mode theory of waveguide optics, the optical intensity transfer function of the microring resonator with parallel-coupled structure was deduced and the transmission spectrums were simulated numerically. The results show that when the radius of resonator of resonator is 0.79μm, the straight waveguide width is 0.3μm and the ring waveguide width is 0.25μm, the filter with full wave at half maximum (FWHM) of 7 nm can be achieved, which also has an exceeding free spectral rang 140 nmof and an insertion loss less of 0.5 dB. The performance of this filter can meet the requirements of coarse wavelength division multiplexing system.
