Aim: Modern optics and photonics more and more use quantum physics in the description of optical processes and systems. This is primarily a result of the advances in laser technology and the miniaturisation of optical devices, where interaction between small numbers or even individual atoms and photons occur. The course introduces the student to the semi-classical description as well as to the full quantum theoretical description of the interaction between matter and radiation. These methods are used to describe the light field in various quantum optical states and to describe absorption, emission and photo detection. In the final part of the course we work with the quantum optical description of interference and coherence as well as with noise phenomena in detectors and lasers and phenomena such as squeezed light. The student is also introduced to current problems in quantum optical research. |
