HL 1: Tutorial: Frontiers of Semiconductor Lasers (joint session HL/TUT)

Sunday, March 15, 2020, 16:00–18:40, HSZ 403

The development of semiconductor lasers has been an unprecedented success story and enabled multiple applications which influence many aspects of our modern society. Most important is world-wide optical data communication which relies crucially on semiconductor lasers. Additionally, medical diagnostics and many optical sensing applications are enabled by such optoelectronic devices. In this tutorial, we will highlight the state-of-the-art of semiconductor laser in high-speed data communication and terrestrial and extraterrestrial gas sensing applications. Moreover, we will present recent progress towards the realization and in-depth understanding of thresholdless nanolasers and topological nanolasers as well as cavity-enhanced lasers based on novel quantum materials as active medium.
