我们提出了一种高效的基于四波混频的硅纳米线环波长转换方案，从而不需要对纳米线进行色散工程。相反，我们依赖于环周围克尔磁化率的空间变化来准相位匹配TE偏振场的波长转换过程。我们通过数值模拟表明，在没有色散工程的情况下，这种准相位匹配波长转换方法的性能比传统的波长转换方法高出10d B。
We propose an efficient four-wave-mixing-based wavelength conversion scheme in a silicon nanowire ring whereby no dispersion engineering of the nanowire is required. Instead, we rely on the spatial variation of the Kerr susceptibility around the ring to quasi-phase-match the wavelength conversion process for TE polarized fields. We show through numerical modeling that in the absence of dispersion engineering this quasi-phase-matched wavelength conversion approach can outperform 'conventional' wavelength conversion by as much as 10 dB.
