Abstract:
A laser device comprising:a substrate; a first and second mirror stack, the first mirror stack position proximate to the substrate; a first and second cladding layer, interposing the first and second mirror stack; and an active region, interposing the first and second cladding layer, the active region having at least one quantum well having a first and second face, the first face adjacent to a first barrier layer and the second face adjacent to a second barrier layer, wherein (a) the quantum well includes material selected from the group consisting of GaxIn1âˆ’xSbyP1âˆ’y, AlxIn1âˆ’xSbyAs1âˆ’y, GaxIn1âˆ’xSbyAs1âˆ’y, and AlxIn1âˆ’xSbyP1âˆ’y, where x and y have values ranging from 0 to 1; and (b) each of the first and second barrier layers include material selected from the group consisting of AlsIn1âˆ’sSbtP1âˆ’t, AlsGa1âˆ’sSbtP1âˆ’t, AlsIn1âˆ’sSbtAs1âˆ’t, AlsGa1âˆ’sSbtAs1âˆ’t, and AlSbsPtAs1âˆ’sâˆ’t, where s and t have values ranging from 0 to 1.
