Quantum optics with quantum-dot and quantum-well systems

A theoretical framework is presented to investigate the buildup of quantum-optical correlations in semiconductor quantum-dot and extended quantum-well/quantum-wire systems. As representative examples, the generation of squeezing and the strong light-matter coupling are analyzed. The Fermionic versus Bosonic character of matter is shown to have significant influence on the generic light-matter coupling. The correlation spectroscopy is presented as a suitable tool to demonstrate quantized-light effects via the measurement of the re-emitted light-field quantum statistics. Furthermore, the concept of quantum-optical spectroscopy is discussed as a viable method to directly manipulate strongly interacting many-body states.
