2. Threshold and Temperature Characteristics of InGa(N)As-GaAs Multiple Quantum Well Lasers
Abstract : Semiconductor lasers emitting in the 1.3 μm regime are of interest for applications in access-networks like fiber-to-the-home and radio-over-fiber systems. Suchfiber optical networks are expected to replace the copper-based access-networks currently in use due to a continuously increasing demand on user bandwidth. READ MORE

3. Surface-normal multiple quantum well electroabsorption modulators : for optical signal processing and asymmetric free-space communication
Abstract : Electroabsorption is the physical phenomenon by which the absorption of light in a medium can be controlled by applying an electric field. The Quantum–Confined Stark Effect, which makes the absorption band–edge in quantum wells very field–dependent, together with the strong absorption peak provided by excitons, are the physical foundations for the success of electroabsorption modulators based on quantum well structures in telecommunication networks.

5. Protein Dynamics Studied by NMR Spin Relaxation. Conformational Transitions of a Calmodulin Mutant
Abstract : Binding of calcium to the protein calmodulin leads to molecular reorganization that enables interaction with target peptides and activation of downstream processes. I have studied the dynamics of the calcium-loaded form of a C-terminal calmodulin mutant (E140Q-Tr2C) using NMR spin relaxation experiments. READ MORE
