TUT 5: Frontiers of Semiconductor Lasers (joint session HL/TUT)

TUT 5.3: Tutorium

Sonntag, 15. März 2020, 17:20–18:00, HSZ 403

Theory of Nanolasers — •Christopher Gies — Institut für Theoretische Physik, Universität Bremen, Otto-Hahn-Allee 1, 28334 Bremen

The tutorial will give an introduction to the colorful physics and the modeling of nanolasers. The origin of rate equation will be discussed, focussing on their merits and shortcomings when describing nanolasers. Especially in the high-β regime, spontaneous emission plays an important role even above the laser threshold, emphasizing the impact of fluctuations on the emission characteristics.

The lecture will cover the quantized light field, open-systems approaches for including dissipation, and photon statistics and its relation to photon-correlation fuctions. A strong emphasis will be on how to relate the theoretical approaches to modeling real experiments.
