Claims
- 1. In a semiconductor laser comprising: a planar semiconductor substrate having an elongated groove with slanting planar surfaces in one of its planar surfaces, a semiconductor active layer formed on said one planar surface, an active region aligned with said groove and having planar surfaces parallel to the slanting planar surfaces of said elongated groove, a pair of semiconductor layers sandwiching said active layer and having wider energy gaps than said active layer, and a p-n junction having a first part adjacent said active region and a second part in one of said pair of semiconductor layers.
- 2. A semiconductor laser according to claim 1, in which said one planar surface is in the (100) plane.
- 3. A semiconductor laser according to claim 2, in which said groove is elongated along the <110> direction and has slanting (111) planes.
- 4. In a semiconductor laser comprising: a planar semiconductor substrate having an elongated groove with slanting planar surfaces in one of its planar surfaces, a semiconductor active layer formed on said one planar surface, an active region aligned with said groove and having planar surfaces parallel to the slanting planar surfaces of said elongated groove, a pair of semiconductor layers sandwiching said active layer and having wider energy gaps than said active layer, and a p-n junction having a first part adjacent said active region and a second part in one of said pair of semiconductor layers, in which said one planar surface is in the (100) plane, and in which said groove is oriented in the <110> direction and has slanting surfaces which are nearly in (311) B planes.
