Wavelength-Tunable Semiconductor Lasers

This dissertation presents a multidimensional simulation approach for tunable edge-emitting lasers with a focus on modeling in full three dimensions. It covers a broad range of monolithically-integrated widely- tunable semiconductor lasers. An efficient optical mode solver allows for the solution of the electrothermal-optical device equations in a fully self-consistent manner. To handle the characteristic mode jumps observed in widely tunable lasers, a numerical underrelaxation approach for the coupling between the electrothermal and optical problem was necessary. Comparison of simulated tuning maps to measurements demonstrates that this implementation, which is incorporated into Synopsys simulator TCAD Sentaurus Device, meets the requirements of device engineers.

About the Author
Lutz Schneider received his Masters Degree in Theoretical Physics at the Swiss Federal Institute of Technology (ETH), Z¨urich, in 2001. His diploma thesis was carried out at NASA Ames Research Center, California, and funded by an ETH scholarship. During his studies he spent one year at the University of Edinburgh, Scotland. From 1998 to 1999, he worked in the Theoretical Methods Group at the ABB Corporate Research Center. In 2001, he joined the Computational Optoelectronics Group at the Integrated Systems Laboratory at ETH as a research and teaching assistant. He spent three months at the University of California, Santa Barbara, as a visiting researcher in 2003. His main research interests are in the field of numerical modeling and simulation of semiconductor optoelectronic devices.
