微环耦合谐振光波导中的色散控制模型与数值仿真

Control of dispersion in microring coupled-resonator optical waveguides

本文利用传输矩阵法得到了微环耦合谐振光波导的色散关系,讨论了耦合损耗、传输损耗及耦合系数对微环耦合谐振光波导色散的影响,改变耦合损耗、传输损耗及耦合系数可控制其色散曲线的形状、位置、以及带宽,色散曲线的变化及控制对微环耦合谐振光波导在滤波、光信号延迟及缓存等方面的应用有重要意义.

We calculated the dispersion relation of microring coupled-resonator optical waveguides using transfer matrix method and discussed its dependence on the coupling loss, transmission loss and coupling coefficient. The shape, position and bandwidth of dispersion relation could be controlled by changing the coupling loss, transmission loss and coupling coefficient. The adjustment and control of dispersion relation is important for applications of coupled-resonator optical waveguides in filtering, delay and buffer of optical signal.
