Abstract:
A semiconductor laser may include a substrate, a multi quantum well (MQW) active layer, and an electron stopper layer. The MQW active layer may include a quantum well that is tensile strained and a barrier that is compressively strained. The barrier may be formed from an aluminum gallium indium arsenide phosphide alloy having a first Al x Ga y In (1-x-y) As z P (1-z)  composition. The electron stopper layer may include an aluminum gallium indium arsenide phosphide alloy having a second Al x Ga y In (1-x-y) As z P (1-z)  composition.

Claim (Index 19):
A method of fabricating a semiconductor laser comprising:\n arranging an n-type cladding layer on a substrate; arranging a hole stopper layer on the n-type cladding layer; arranging a multi quantum well (MQW) active layer on the hole stopper layer, the MQW active layer including a quantum well that is tensile strained and a barrier that is compressively strained, where the barrier is formed from an aluminum gallium indium arsenide phosphide alloy having a first Al x Ga y In (1-x-y) As z P (1-z)  composition; arranging an electron stopper layer on a multi quantum well (MQW) active layer; and arranging a current blocking material adjacent to the n-type cladding layer, hole stopper layer, MQW active layer, and electron stopper layer, wherein the electron stopper layer is configured to reduce oxidation and form an interface with the current blocking material, and includes an aluminum gallium indium arsenide phosphide alloy having a second Al x Ga y In (1-x-y) As z P (1-z)  composition.
