Intersubband transitions in quantum wells are transitions between states created by quantum confinement in ultra-thin layers of semiconductors. Because of its inherent taylorability, this system can be seen as the "ultimate quantum designer's material".

The course presents fundamental aspects of light-matter interaction in semiconductor materials, from basic research topics to opto-electronic devices.

In this lecture, the goal is to review the physics behind mode-locking in these various devices, as well as discuss the most important novelties and applications of the newly developed sources.

The goal of the Physics II class is an introduction to quantum mechanics

Classical and semi-classical introduction to Quantum Electronics. Mandatory for further elective courses in Quantum Electronics. The field of Quantum Electronics describes propagation of light and its interaction with matter. The emphasis is set on linear wave and beam propagation in dispersive media, interference, diffraction, optical anisotropic materials, waveguides and lasers.

In this lecture, we would like to review new developments in the emerging topic of quantum optics in very strongly confined structures, with an emphasis on sources and photon statistics as well as the coupling between optical and mechanical degrees of freedom.
