    摘要: The semiconductor light-emitting element uses a compound semiconductor quantum well structure comprising a well layer, and barrier layers between which the well layer is sandwiched, as an active layer. In the adjacent well layer and barrier layers of the semiconductor light-emitting element, the well layer has in part a doped well region to which an n-type impurity is added at the interface with the barrier layer on the electron injection side, and in the vicinity of this interface, and the barrier layer has a doped barrier region to which the n-type impurity is added at least at the interface and in the vicinity of this interface.

    摘要: An improved semiconductor laser device is provided which has a small distance between laser light emitting spots. Such laser device comprises i) a first light emitting element including a laser oscillation section provided with a ridge waveguide and formed by forming a group-III nitride semiconductor film on a substrate, an insulating layer and an ohmic electrode layer, ii) a second light emitting element including a laser oscillation section provided with a waveguide and formed by forming III–V compound semiconductor film, an insulating layer and an ohmic electrode layer. By virtue of the adhesive metal layer interposed between the two ohmic electrode layers, the two laser oscillation sections are combined together, thereby forming the improved semiconductor laser device which has a small distance between laser light emitting spots of the two laser oscillation sections.
