We propose a relay ring resonator structure which comprises multiple cascaded microring resonators, in which the drop waveguide of a microring resonator is also the input waveguide of the subsequent microring resonator, and so forth. Thus, the transmission response of the relay ring resonator structure has sharp peaks, high out-of-band rejection ratios, and long group delays. A relay ring resonator structure comprising 90 microrings is fabricated on silicon nitride wire waveguides. The simulation and experimental results are in good agreement.
我们提出了一种中继环形谐振器结构，它由多个级联的微环谐振器组成，其中一个微环谐振器的下路波导也是后续微环谐振器的输入波导，依此类推。因此，中继环形谐振器结构的传输响应具有尖锐的峰值、高的带外抑制比和长的群延迟。在氮化硅线波导上制作了一个包含90个微环的中继环形谐振器结构。仿真和实验结果吻合良好。
