Abstract

Waveguide quasi-phase matching second-harmonic generation (QPM-SHG) using an organic molecular crystal as a nonlinear material was demonstrated for the first time. The device is constructed with an array of SiN channel guides with grooves of a fan-out grating pattern and mNA single crystal grown over the waveguides. A normalized efficiency of 0.04%/W was obtained in an experiment involving frequency doubling of CW Nd:YAG laser light.<>
