Semiconductor laser and method of manufacturing the same. |
摘要 |
In a semiconductor laser having a p-type cladding layer consisting of GaInP or AlGaInP, an operating voltage is decreased. In a semiconductor laser formed on a GaAs substrate and having a p-type cladding layer consisting of GaInP or AlGaInP and a p-type contact layer consisting of GaAs or GaInAs, p-type buffer layers are formed between the p-type cladding layer and the p-type contact layer, which consists of a compound containing both arsenic (As) and phosphorus (P) and having a medium bandgap between those of the two layers. <IMAGE> |
