Influence of growth conditions on the optical gain of 1.3 /spl mu/m (GaIn)(NAs)/GaAs lasers

Abstract

We investigate the optical gain of GaInNAs/GaAs laser structures and demonstrate that the gain critically depends on the growth conditions. This observation rises the possibility to tailor the optical properties of GaInNAs/GaAs lasers by the growth conditions or even by subsequent annealing procedures without changing the nominal material composition.
