Micro- and Nano-Photonics Group of Prof. Hans-Peter Wagner
Artificial semiconductor nanostructures as well as organic structures with dimensions down to nanometer size have attracted significant attention due to new device applications in photonics, lasing, optoelectronics and information technology. The next challenge in this research area is to fabricate and understand hybrid organic/ and plasmonic metal/organic/semiconductor nanostructures as well as photonic crystals where various aspects of the optical and electrical properties may be controlled through active design of these materials and nanostructures.
In my research group we are designing and fabricating such artificial nanostructures and we are trying to better understand the coherent and incoherent relaxation dynamics of excited carriers and excitons as well as the lasing characteristics in these structures with modern optical investigation methods. The result of our research is not only of fundamental physical interest but is of crucial importance for many potential optoelectronic applications including photovoltaics, lighting, holographic imaging, transformation optics, single nanowire lasing and photonic crystal lasing. My research programs integrate teaching and research by providing training for graduate and undergraduate students in areas such as semiconductor physics, ultrafast optics, nanotechnology and information technology. This training will prepare students for a wide range of careers in research and development in corporate, government and university laboratories.
