Open RQC colloquium. Lecture 16

The Sixteenth lecture "Bosonic Lasers" in "Open RQC colloquium" will be held in National University of Science and Technology MISIS(Moscow, Leninskiy prospekt 4) lecture hall № Б-536 (5th floor), on 27th of January 2017 at 10:00 a.m by Alexey Kavokin, Professor at the University of Southampton (UK), Scientific Director of the Mediterranean Institute of Fundamental Physics (Italy), Head of the Spin Optics laboratory at the State University of St-Petersburg and and Quantum Polaritonics Group Lead in the Russian Quantum Center (Russia).


LASER stands for Light Amplification of Stimulated Emission of Radiation. Bosonic lasers are coherent light sources where radiation is emitted spontaneously, contrary to the definition above. Similarly to conventional, fermionic, lasers, bosonic lasers emit a coherent and monochromatic light, but the mechanism of light generation is very different. It involves the stimulated scattering of crystal quasiparticles: excitons to the light-matter bosonic condensate which may be viewed as a superfluid droplet of liquid light. Such condensates are formed in semiconductor microcavities due to the strong coupling of excitons and cavity photons. Nowadays, bosonic lasers operate at room temperature. They are characterised by ultralow threshold currents and promise multiple applications in optical integrated circuits, logic elements, switches etc. Bosonic Cascade Lasers have been proposed as compact and highly efficient sources of terahertz radiation. I will overview 20 years of research on Bosonic lasers.


Alexey Kavokin obtained a PhD in physics 1993 from the Ioffe Physico-Technical Institute of Russian Academy of Sciences. Since the beginning of 1990s he is doing a theoretical research in Polaritonics: physics of liquid light. In 1998 he became a Professor at the Blaise Pascal University (Clermont-Ferrand, France). In 2005 he moved to Southampton (UK) where took a Chair of Nanophysics and Photonics. Since 2010 A. Kavokin is a Scientific Director of the Mediterranean Institute of Fundamental Physics. After winning a Megagrant of the Russian Government in 2011 A. Kavokin leads the Spin Optics laboratory at the State University of St-Petersburg. This laboratory (currently 32 staff) is one of the world leaders in the spin dependent phenomena in optics of semiconductor nanostructures. Since 2013 A. Kavokin is a Head of Quantum Polaritonics group at the Russian Quantum Center. He also serves as an Editor of the "Superlattices and Microstructures".


Please don't forget to take passport for entering to the University. We will meet you at the guard desk.
