- Abstract
In this paper we investigate the optical gain seen by the polarization modes for each of Transverse Electric (TE) and Transverse Magnetic(TM) of GaAs/Al0.32Ga0.68As quantum-well lasers. The factor confinement and modal gain of proposed structure also have been simulated. Comparison between the two structures (single and multiple quantum) were conducted in the effort to evaluate and understand their behavior. Results show that the optical gain offers a better value in TE mode than in TM mode. As a result of being on higher standard and having a better performance in both cases thus this study conclude that the multiple quantum well structures are a better designed choice compared to single quantum well structure.
