Control of dispersion in microring coupled-resonator optical waveguides
微环耦合谐振光波导中的色散控制模型与数值仿真

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.
