利用传输矩阵法得到了微环耦合谐振光波导色散关系的一般表达式,并由色散关系出发讨论了光脉冲在微环耦合谐振光波导中传输时的线性特性,包括带宽、群速度、色散和线性相位变化,这些特性对微环耦合谐振光波导在光通信和光传感领域的应用有重要意义.
The general expression of dispersion relation of microring coupled-resonator optical waveguides was obtained using transfer matrix method.Based on the dispersion relation the linear characteristics of optical pulse propagation in microring coupled-resonator optical waveguides was discussed with respect to the bandwidth,group velocity,dispersion and linear phase shift.These characteristics are important for applications of coupled-resonator optical waveguides in optical communications or as optical sensors.
