We demonstrate four-wave mixing in silicon-on-insulator coupled-resonator optical waveguides consisting of 35 and 65 microring resonators, using a cw pump with coupled power below 20 mW and observed parametric conversion across more than 10 THz. The conversion efficiency is enhanced by +16 dB relative to a silicon straight waveguide of equivalent length, due to the slowing factor of the coupled-resonator structure.
我们在由 35 个和 65 个微环谐振器组成的绝缘体上硅片耦合谐振器光波导中演示了四波混频，使用耦合功率低于 20mW 的连续波泵浦，并观察到超过 10THz 的参量转换。由于耦合谐振器结构的慢光因子，转换效率相对于等效长度的硅直波导提高了 +16dB。
