ABSTRACT:
An optical resonator including a lower multilayer reflector and an upper multilayer reflector is arranged on a substrate. A strained active layer having a multiple quantum well structure formed with a quantum well layer and a barrier layer is arranged in the resonator. A current confinement layer including a selectively oxidized portion is arranged on an upper side of the strained active layer. The current confinement layer is arranged at a position where a strain in the selectively oxidized portion influences the strained active layer.
