| 摘 要： | 对耦合微环谐振腔光波导中的有限尺寸效应进行了研究.在CMROW两端引入抗反射结构,采用数值方法对抗反射中的三个交叉耦合系数进行了优化,消除了透射谱和群时延谱的有限尺寸效应.数值计算得到了弱耦合和强耦合情况下抗反射结构中优化交叉耦合系数的拟合公式,可以直接计算出消除有限尺寸效应时所需的优化参量.

| Abstract: | The finite-size effects in Coupled Microring Resonator Optical Waveguide(CMROW)are investigated.The transmission and normalized group delay are optimized by inserting antireflection structures in both ends of CMROW.The fit formulas of optimized cross-coupling coefficients in antireflection structures are obtained for both weak coupling and strong coupling.With the fit formulas,the suitable cross-coupling coefficients can be calculated directly and easily.The simulation results show that,optimization can be ... |
