Light emitting semiconductor element capable of suppressing change of driving current |
摘要 |
A light emitting semiconductor element comprises a first additive layer which is added into a cladding layer or a middle layer. The first additive layer has a lattice constant which is different from a lattice constant of a semiconductor substrate. The light emitting semiconductor element is attached to a heat sink to form a laser device. The heat sink gives deformation to the light emitting semiconductor element. The first additive layer generates strain therein and suppresses influence of the deformation.
