Abstract

Second harmonic conversion from 1550 nm to 775 nm with an efficiency of 400% W⁻¹ is demonstrated in a gallium phosphide (GaP) on oxide integrated photonic platform. The platform consists of doubly-resonant, phase-matched ring resonators with quality factors Q ∼ 10⁴, low mode volumes V ∼ 30(λ/n)³, and high nonlinear mode overlaps. Measurements and simulations indicate that conversion efficiencies can be increased by a factor of 20 by improving the waveguide-cavity coupling to achieve critical coupling in current devices.
