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 17):
The semiconductor laser of  claim 16 , wherein a lattice mismatch of the quantum well relative to a lattice constant of the substrate is within 2%, and a lattice mismatch of the barrier relative to the lattice constant of the substrate is within 2%.
