The dispersion of the waveguides that constitute microring resonators can considerably affect the dispersion characteristics of coupled-resonator optical waveguides (CROWs). We derive expressions for CROW dispersion and group delay for silicon-on-insulator microring CROWs, showing both theoretically and experimentally the band-to-band dependence of the bandwidth and group delay on the dispersion properties of the constituent single-mode silicon waveguide.
构成微环谐振器的波导的色散会对耦合谐振器光波导（CROW）的色散特性产生相当大的影响。我们推导出了用于绝缘体上硅微环 CROW 的 CROW 色散和群延迟的表达式，从理论和实验上展示了带宽和群延迟的能带间依赖性与构成单模硅波导的色散特性之间的关系。
