Abstract
Recent progress in design and fabrication of quantum cascade lasers have brought these devices to operating temperatures in the Terahertz very close to room temperature and very comfortably in the range of Peltier coolers1, with the published maximum operating temperature up to 250K2. We show also that these devices are able to operate as optical frequency combs3 with a great diversity in output waveform and operation modes4.

Bio
Jérôme Faist was born in Switzerland and obtained his Ph.D. in Physics in 1989 from the Swiss Institute of Technology in Lausanne. He then worked successively at IBM Rueschlikon (89-91) and Bell Laboratories (91-97). He was nominated full professor in the physics institute of the University of Neuchâtel (1997) and then full professor in the ETH Zurich (2007).
His key contribution to the development of the quantum cascade laser was recognized by a number of awards. His present interests include the development of mid-infrared and terahertz quantum cascade lasers and frequency combs and the physics of strong light-matter coupling in metallic resonators.
