ABSTRACT:
In a semiconductor laser device including a multiple quantum well active layer formed by well layers and barrier layers alternately, and an n-type separate confinement heterostructured layer and a p-type separate confinement heterostructural layer sandwiching the multiple quantum well active layer, the n-type separated confinement heterostructured layer is thicker than the p-type separated confinement heterostructured layer.
