Design optimization of GaInNAs quantum wells for long wavelength VCSEL

Analysis of material composition effect and material gain are performed to investigate GaInNAs quantum wells performance for application in long wavelength Vertical-Cavity Surface-Emitting Laser (VCSEL) operating at 1310 nm wavelength. The optimized GaInNAs active region is then incorporated into double intracavity device structure for VCSEL analysis. The long wavelength GaInNAs VCSEL exhibits sub-miliampere operating current and single-mode emission at 1310 nm wavelength.
