Research interests:

His current research interests include modeling and theoretical investigation of photonic, nanoelectronic and spintronic components and systems. In the field of photonics, his research is related to nanostructure lasers, amplifiers, photodetectors, terahertz optical receivers and sources. In particular, he deals with band structure calculation of quantum confined heterostructures based on the k.p theory, optical gain calculation, dynamics of lasers and transport effects in lasers, optical amplifiers and switches. He is also interested in physics and design of mid-infrared and terahertz optical receivers and sources based on intersubband transitions in quantum confined heterostructures. His initial research in photonics was related to modeling of dynamic characteristics of PIN and MSM photodetectors (PDs), resonant-cavity enhanced MSM-PDs and traveling wave MSM-PDs. In field of nanoelectronics and spintronics his research is directed toward fundamental investigation of the Rashba and Dresselhaus effect in low-dimensional semiconductor heterostructures and their implementation in spin-based nanodevices. This research is based on 8×8 k.p theory, which provides a possibility to study interplay between these two effects on spin flipping and precession in the conduction and the valence band of semiconductor nanostructures. His interest also lies in photonic communications, comprising investigation of coherent detections schemes, nonlinear effects and four-wave mixing in semiconductor nanostructures, photonics integrated circuits and widely-tunable integrated transmitters, receivers, and wavelength converters.

Short CV :

Dejan Gvozdić received the B.S., M.S. and Ph.D. degrees in electrical engineering from Belgrade University, Yugoslavia, in 1989, 1992 and 1995, respectively. He joined the School of Electrical Engineering, University of Belgrade in 1989, where he is now a professor of Physical Electronics, Statistical Physics, Optical Communications and Quantum Electronics. In 1998 and 2001 he was with the Institut für Halbleitertechnik, TU Braunschweig (Prof. Dr. A. Schlachetzki), Germany, working there on optical switches and quantum wire lasers. After having spent almost two years in Belgrade (2001-2003) he moved to Stockholm in September 2003. He has begun to work there as a research associate at the Laboratory of Optics, Photonics and Quantum Electronics of the Royal Institut of Technology, Stockholm, Sweden, with Dr. Ulf Ekenberg in the field of spintronics in semiconductor nanostructures. From 2006 to 2009 he was a vice dean of the School of Electrical Engineering.
