Four-wave mixing in GaAs/AlGaAs semiconductor lasers
TLDR
In this paper, a simple description of FWM in terms of frequency-modulation-induced sidebands is discussed, and population pulsations of the inverted carrier system due to nonlinear beat frequency inversion modulation are identified as the microscopic origin.Abstract:
Studies on high-efficiency four-wave mixing (FWM) in semiconductor lasers up to detuning frequencies of about 21 GHz are discussed. Population pulsations of the inverted carrier system due to nonlinear beat frequency inversion modulation are identified as the microscopic origin. A simple description of FWM in terms of frequency-modulation-induced sidebands is discussed. >read more

Analysis of gain suppression in undoped injection lasers
Minoru Yamada,Yasuharu Suematsu +1 more
TL;DR: In this paper, an analysis of gain suppression in injection lasers with an undoped active region and an index guiding structure is presented. And the results of this analysis explain the experimental data of well-designed injection lasers which have an unweighted active region, which is crucial for the operation of injection lasers in a single longitudinal mode.
