Efficient four-wave-mixing-based wavelength conversion in silicon nanowire rings without dispersion engineering
Book Contribution - Book Chapter Conference Contribution
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.
