Abstract:
1. A semiconductor light emitter, comprising: a quantum well active layer which includes nitrogen and at least one other Group-V element; barrier layers which are provided alongside said quantum well active layer, wherein said quantum well active layer and said barrier layers together constitute one active layer; upper and lower reflectors which are respectively provided on upper and lower sides of said one active layer, wherein said one active layer and said upper and lower reflectors together constitute a resonator structure; a GaAs substrate on which said resonator structure is formed; and spacer layers which are provided between said upper and lower reflectors and said one active layer, wherein said barrier layers are formed of a Group-III-V mixed-crystal semiconductor that includes nitrogen and at least one other Group-V element, and said spacer layers are mainly formed of a material having a larger band gap than GaAs, and wherein said semiconductor light emitter is a surface emitting semiconductor laser.
