Patent abstract
A laser diode is provided. The laser diode has a structure in which reflective index of an n-cladding layer formed on a first face of the active layer is higher than that of a p-cladding layer formed on a second face. This asymmetric waveguide structure suppresses extension of field into the p-cladding layer thus reducing free carrier absorption in the p-cladding layer.
