For a given excitation density, the gain in the (GaIn)Sb material system considerably exceeds that of a comparable equivalent (GaIn)As/GaAs structure. The physical reasons for this high gain are analyzed and attributed mostly to band structure effects.enlaser gainoptical gainoptischer GewinnGaSbmicroscopic calculationMikroskopische Theoriediode laserDiodenlaser667621journal article
