Influence of facet reflectivity on the differential gain and K-factor in high-speed GaAs/AlGaAs and InGaAs/GaAs MQW lasers

Other Title
Einfluss der Spiegelreflektivität auf den differentiellen Gewinn und K-Faktor in Hochgeschwindigkeits-GaAs/AlGaAs und InGaAs/GaAs -MQW- Lasern
Abstract
The intrinsic modulation response of semiconductor lasers is dependent on the differential gain, which determines the relaxation frequency for a given current density, and the damping factor, K, which limits the ultimate 3-dB bandwidth. We investigated the dependence of both parameters in GaAs/AlGaAs and pseudomorphic InsubyGasub1minusyAs/GaAs multiple-quantum-well lasers on the threshold gain by measuring the relative intensity noise power spectra of lasers with different facet reflectivities and cavity lengths.
