Abstract

Four-wave mixing is observed in a silicon W1 photonic crystal waveguide. The dispersion dependence of the idler conversion efficiency is measured and shown to be enhanced at wavelengths exhibiting slow group velocities. A 12-dB increase in the conversion efficiency is observed. Concurrently, a decrease in the conversion bandwidth is observed due to the increase in group velocity dispersion in the slow-light regime. The experimentally observed conversion efficiencies agree with the numerically modeled results.

摘要

在硅W1光子晶体波导中观察到了四波混频现象。测量了闲频光转换效率的色散依赖性，并表明在呈现慢群速度的波长处其有所增强。观察到转换效率提高了12分贝。同时，由于慢光区域中群速度色散的增加，观察到转换带宽减小。实验观察到的转换效率与数值模拟结果相符。
