The purpose of the course is to teach light and matter interactions starting with classical harmonic oscillator models such as the Lorentz model and building up complexity to pass to modern semiconductor lasers such as VECSELs and Quantum Cascade lasers and phenomena of coherent light and matter interaction as they are encountered in polariton lasers. In this path students will be shown many concepts covering classical optics, quantum optics but also semiconductor physics, the target is to understand the variety of models and concepts needed to understand light and matter interaction and how our understanding is advancing technology.
The course is suitable for students of the Departments of Chemistry and Materials science and Technology (TEMY) who are in their fourth year.
