Abstract :
Summary form only given. GaAs-based 1.3 /spl mu/m vertical cavity surface emitting lasers (VCSELs) are highly desirable for optical data communication. One of the most promising approaches is to use GaAsSb/GaAs quantum wells as the laser active region. Due to the large compressive strain necessary for the GaAsSb layer to reach 1.3 /spl mu/m, it can be prohibitive to use multiple QWs without compensating the strain. This paper reports GaAsSb/GaAs active layers sandwiched by tensilely strained GaAsP layers. The larger bandgap, of the GaAsP layers also provide stronger electron confinement.
