This Ph.D. thesis is divided into two parts. In the first chapters a broadband optical model for optoelectronic devices is derived and implemented into an existing device simulator. This novel model is then employed for two- and three-dimensional electro-optothermal simulations of various super-luminescent light-emitting diodes. After a calibration step measured and simulated emission characteristics agree very well for different device designs. In the last chapters of this thesis the Ultra-Weak Variational Formulation is shown to be an efficient approach to numerically analyze the radiation characteristics of optically large structures. It is illustrated how information reduction techniques can be applied to significantly reduce the computational cost without affecting the accuracy of the solution.
About the Author
Martin Loeser was born in Donauwoerth, Germany, in 1977. From November 1997 to February 2003 he studied Electrical Engineering at the Technical University of Munich (TUM). During his studies he spent one year at the University of Sydney, Australia, as an exchange student. In parallel, from 2000 to 2002, he studied Technology Management at the Center for Digital Technology and Management at the TUM. In September 2004 he joined the Computational Optoelectronics group of the Integrated Systems Laboratory at the Swiss Federal Institute of Technology (ETH) as a research and teaching assistant. His research focuses on numerical modeling of broadband optoelectronic devices and on novel Finite Element techniques for electromagnetics.
Keywords: numerical modeling, broadband optoelectronic devices, novel Finite Element techniques, electromagnetics.
