英文摘要 | Semiconductor diode lasers include an aluminum free active region including at least one active layer having a general composition In(1-x)GaxAsyP(1-y) where 0=y=1; two confinement layers bounding the active region and having a general composition In(1-x)(Ga(1-z)Alz)xP wherein aluminum content z may be zero; and a lower cladding layer, and at least one upper cladding layer adjacent the confinement layers. The cladding layers have the same general composition as the adjacent confinement layer, but always have a finite aluminum content. The aluminum content of the cladding layers is selected such that the cladding layers have a energy bandgap greater than the energy bandgap of the confinement layers. |
