Content of the book



This dissertation deals with the TCAD simulation and analysis of long-wavelength VCSELs. The simulations are performed with the commercial device simulator Synopsys Sentaurus Device. A thorough calibration of the electro-opto-thermal properties of a long-wavelength VCSEL with tunnel junction is presented. The temperature-dependence of external device characteristics, such as threshold current, thermal roll-over, and single-mode stability is investigated in detail. Special emphasis is laid on the understanding of the mode-switching behavior of the VCSEL. This thesis closes with a design optimization improving the maximum single-mode output power.

About the Author

Alexandra Baecker was born in Vienna, Austria, in 1980. She received the Dipl.-Ing. degree in Electrical Engineering from Vienna University of Technology, Austria, in 2004. From 2004 to 2009 she was a research and teaching assistant at the Integrated Systems Laboratory (IIS), ETH Zurich, Switzerland. For six months in 2007, she was a visiting researcher at the Laboratory of Nanostructures (Institute of Quantum Electronics and Photonics) at EPF Lausanne, Switzerland. Her research interests include numerical simulation and characterization of optoelectronic devices, especially vertical-cavity surface-emitting lasers (VCSELs).
