Spectral effects in short pulse pump-probe measurements

Spectral effects arising from linear gain dispersion are shown to strongly influence the ultrafast gain dynamics measured in active semiconductor waveguides using the pump-and-probe technique. Measurements on a AlGaAs amplifier under varying amounts of gain dispersion are in good agreement with a si...

Zusammenfassung:Spectral effects arising from linear gain dispersion are shown to strongly influence the ultrafast gain dynamics measured in active semiconductor waveguides using the pump-and-probe technique. Measurements on a AlGaAs amplifier under varying amounts of gain dispersion are in good agreement with a simple analytical theory derived from semiclassical density matrix equations.
