基于折射率、损耗或波导环耦合强度的变化，导出了微环调制器传输的动态模型，以研究强度调制带宽的限制。如果波导-环耦合强度变化，而不是环的折射率或损耗变化，则调制带宽接近自由频谱范围频率是可能的。结果表明，通过控制耦合，可以设计出具有高质量因数的谐振调制器，其工作频率远远大于谐振器线宽。(C) 2008美国光学学会
A dynamic model for the transmission of a microring modulator based on changes in the refractive index, loss, or waveguide-ring coupling strength is derived to investigate the limitations to the intensity modulation bandwidth. Modulation bandwidths approaching the free spectral range frequency are possible if the waveguide-ring coupling strength is varied, rather than the refractive index or loss of the ring. The results illustrate that via controlled coupling, resonant modulators with high quality factors can be designed to operate at frequencies much larger than the resonator linewidth.
