Dynamic Franz-Keldysh effect and its applications
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 ...
Space-time cross correlations of diffuse broadband terahertz waves
We describe observations of the amplitude and phase of an electric field diffusing through a three-dimensional random medium by using Terahertz Time-Domain Spectroscopy. These measurements are spatially resolved with a ...
