  • Patent number: 7903711
    Abstract: A separate confinement heterostructure includes a quantum-well layer bounded by an n-side waveguide layer and a p-side waveguide layer. The waveguide layers guide a lasing mode of the heterostructure. The n-side waveguide layer is composed of indium gallium phosphide (InGaP) and the p-side layer is composed of aluminum gallium arsenide (AlGaAs). The heterostructure is configured such that more than 80% of the optical mode propagates in the n-side waveguide layer.
