1.  Prof. Yury Yakovlev, Ioffe Physico-Technical Institute, RUSSIA
Late-Breaking Results: Highly tunable whispering gallery mode semiconductor lasers with controlled absorber
Speaker Biography: Yury P.Yakovlev was born on October 17, 1939. He graduated with a M.Sc. degree from the Leningrad Electrical Engineering Institute in 1962 and jointed Ioffe Physico-Technical Institute in 1969. He received his Ph.D. degree in 1978 and the Doctor of Science degree in 1995 both in physics and mathematics from Ioffe Institute. His main research interests are technology and researches of narrow band gap III-V solid alloys heterostructures and optoelectronic devices (LED, Lasers and Photodiodes). In 1995, Yury Yakovlev organized and headed the Laboratory of Infrared Optoelectronics (LIRO) in Ioffe Institute. Prof. Yury P. Yakovlev has authored or co-authored 80 patents, over 200 papers, reviews and book chapters.

Summary: Tunable semiconductor lasers with controlled absorber based on GaInAsSb/GaAlAsSb quantum well heterostructure was fabricated and experimentally studied. The emission wavelength of these lasers shifts from 2.24 to 2.28 μm when the bias on the control contact decreases from the voltage equal to that on the main electrode to 0 V when the control contact is grounded. The principle of operation of such a device is given
