| 英文摘要 | A semiconductor laser device capable of emitting lights of different wavelengths has a substrate, a first light-emitting layer provided on the substrate, and a second light-emitting layer provided on the substrate and having a greater band gap than the first light-emitting layer. A barrier layer is disposed between the first and second light-emitting layers. The barrier layer has a band gap greater than those of the first and second light-emitting layers. The band gap and the thickness of the barrier layer are determined to be large enough to create, in response to injection of carriers to the light-emitting layers, a state in which the carrier density in the second light-emitting layer is made higher while the carrier density in the first light-emitting layer is made lower than those which would be obtained when the barrier layer is omitted. The device further has a pair of cladding layers sandwiching therebetween the first light-emitting layer, the barrier layer and the second light-emitting layer, the cladding layers having smaller refractive index values than the first and second light-emitting layers. The device further has electrodes for supplying electrical currents to the first and second light-emitting layers. |
