All-optically induced quasi phase matching in SiN waveguides for second harmonic generation enhancement
2017
CLEO: Science and Innovations 2017
We report more than 30dB second harmonic generation enhancement in SiN waveguide by all-optical writing of a persistent χ(2) grating. Phase matching peaks are observed for different writing wavelengths.
