摘要: In a semiconductor laser device, a plurality of light-emitting elements emitting light with different wavelengths are integrated on a substrate. Each of the light-emitting elements includes, on the substrate, an active layer and cladding layers respectively provided on top and bottom of the active layer. One of the cladding layers provided on top of the active layer is an upper cladding layer having a mesa ridge portion. An etching stopper layer for forming the ridge portion is interposed between the ridge portion and the other portion of the upper cladding layer. The thickness of the etching stopper layer varies among the light-emitting elements.

摘要: A semiconductor laser device includes a first cavity and a second cavity formed apart from each other over a semiconductor substrate. The first cavity includes a first buffer layer and a first semiconductor layer including a first active layer, and the second cavity includes a second buffer layer and a second semiconductor layer including a second active layer. A window structure is provided in a region near an end face of each of the first semiconductor layer and the second semiconductor layer. A band gap of the first buffer layer is greater than that of the first active layer, and a band gap of the second buffer layer is greater than that of the second active layer.

A p-type cladding layer made of p-type AlGaInP in the red laser portion and a p-type cladding layer made of p-type AlGaInP in the infrared laser portion have a ridge stripe portion having a light emitting point. A current block layer made of SiNx is formed on both sides of each ridge stripe portion, and a strain relaxing layer made of ZrO2 is selectively formed on an outer side of each ridge stripe region on the current block layer.
