摘要
对硅基微环光学谐振器建立了一种基于Spice的器件模型,该模型可以作为集成光路的基本元件应用于集成光路的计算机模拟。应用该模型分析了双环以及多环光学滤波器光路。计算得到双环光学滤波器耦合系数与系统增益以及3 dB带宽的关系,结果表明,微环数目越大,谐振特性越陡峭,具有更好的滤波特性。
A novel Spice model of silicon-based micro-ring resonator is introduced,which can serve as a basic component of integrated optical path. Some basic applications of series-coulped structure,such as double-ring and muliple-ring filter,are analyzed. In addition,the tradeoff between optical gain and 3 dB bandwidth characteristics are investigated. Results show that the larger number of rings,more precipitous resonant peak will produce the better device filtering characteristic.
