ABSTRACT:
A frequency-doubled, edge-emitting semiconductor laser includes a separate confinement heterostructure surmounted by a waveguide including a converting layer of a periodically poled, optically nonlinear material. Fundamental radiation generated in the heterostructure is directionally coupled from the heterostructure into the waveguide, is converted to second-harmonic radiation in the converting layer and is delivered from the waveguide as output radiation. In one example, a distributed Bragg grating is included at an interface between the heterostructure and the waveguide for facilitating coupling of fundamental radiation from the heterostructure into the waveguide.
