Quasi-Phase Matched Second Harmonic Generation in Orientation-Patterned Gallium Phosphide Waveguides
Résumé
We demonstrate continuous-wave second-harmonic generation from 1.5 µm lasers in orientation-patterned gallium phosphide waveguides with 200 %/W.cm2 efficiency, to our knowledge the highest reported conversion efficiency in this platform. © Optica Publishing Group 2022, © 2022 The Author(s)
