Optical gain evaluation in GaInAsP quantum-well lasers: A comparison of the different growth techniques
Abstract
GaInAsP quantum-well lasers are usually built by keeping constant the anion (CY lasers) or the cation (CX lasers) concentration into wells and barriers. We interpret the higher performances of CY-laser structures comparatively with CX structures by the significant increase of the effective nonradiative lifetime coming from the reduced overlap between the electron and hole gases.
