Abstract
An SDH semiconductor laser has a semiconductor substrate which is (100) oriented and has a stripe ridge thereon, first and second cladding layers disposed on stripe ridge, an active layer sandwiched between the first and second cladding layers, and an electrode held in electric contact with the first and second cladding layers and the active layer. The stripe ridge extends in a <01-1> axis direction, and the first and second cladding layers and the active layer jointly provide a semiconductor stripe region of triangular cross section sandwiched between (111) A faces. A method of manufacturing the SDH semiconductor laser is also disclosed.
