Abstract:We have theoretically investigated the band structure engineering and optical gain spectra of dilute-bismide and bismide-free respectively in GaAsBi/GaAsP and GaAs/GaAsP laser structures. Subsequently, a type-I strain-compensated GaAs 0.97 Bi 0.03 /GaAs 0.7 P 0.3 quantum well heterostructure which was optimized in terms of compositions and thicknesses has been studied by solving Schrodinger equation. We found that the incorporation of a small fraction of bismuth in the laser active region enhances significantl… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
