FOR 485:  Quantum Optics in Semiconductor Nanostructures

• Subject Area: Physics
• Term: from 2002 to 2008
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5469731

The goal of the research unit is to combine the methods of Quantum Optics with the recent developments in Semiconductor Physics made possible by advances in design and preparation of low dimensional semiconductor structures on a nanoscopic scale. This new and innovative field of Semiconductor Quantum Optics, which has emerged in the last few years, offers the possibility of both a fundamental understanding of matter-light interaction on a quantum level and the realization of unique devices for quantum optic experiments. The work will concentrate on the following areas:-- generation of squeezed light from semiconductors,-- cavity Quantum Electrodynamics in the weak and strong coupling regime,-- generation of entangled photons, and-- quantum dot laser structures with large spontaneous emission factor. In the research unit, we look for answers to questions on the physical mechanisms, demonstrate the various quantum optical effects in semiconductor structures and provide a thorough understanding by a quantum theoretical treatment of both semiconductor and light field. Besides these interests from basics physics, the developed concepts might be transferred into future applications such as high efficiency quantum light sources or single photon emitters.
