Abstract

In this dissertation we study the dynamic Franz-Keldysh effect (DFKE) in GaAs. We observe the salient features of DFKE viz., below bandgap absorption and oscillations above the band gap, in our experiments. We also report the first observation of a large photoinduced transparency which represents a novel coherent phenomenon based on the DFKE and agrees well with the theoretical predictions. Finally we propose schemes making use of this effect to realize all-optical wavelength conversion required in high speed optical networks based on wavelength division multiplexing (WDM).
