830-nm InGaAs Quantum Well Lasers With Very Low Beam Divergence
We report on our design and fabrication of 830-nm high-power semiconductor lasers with very low beam divergence. Here, we propose a novel approach in which by combining asymmetric waveguide and a feature called “pins” together, we were able to design an optimize epi structure,...
