Project Head: Prof. Dr. Alexander Mielke , Priv.-Doz. Dr. Uwe Bandelow, Priv.-Doz. Dr. Frank Schmidt
Investigators: Dr. Thomas Koprucki, Dipl.-Phys. Alexander Wilms, Dr. Paul Racec (4/2008 - 6/2009)

Description:

In this project between WIAS and ZIB there will be developed, analyzed and implemented numerically semiclassical models for 3D VCSELs. The aim is an efficient simulation for VCSELs with complex 3D structure, in order to get a deeper insight in their functionality and to understand the interplay between different physical phenomena at this scale. The challenge will be to construct a hierarchy of models for a self consistent description of charge transport, temperature distribution and optical fields, and the implementation of these models in efficient simulation tools.
