LPE In1−xGaxP1−zAsz (x∼0.12, z∼0.26) DH laser with multiple thin-layer (<500 Å) active region

Abstract
A liquid‐phase‐epitaxial (LPE) double‐heterojunction (DH) laser structure with an ∼1‐μm ’’active region’’ consisting of ≳20 In1−xGaxP1−zAsz and InP lattice‐matched thin layers is described. The thin‐layer dimensions are small enough (<500 Å) to make quantum size effects relevant.
