 Abstract: Semiconductor nanostructures such as quantum dots (QDs) have offered unique opportunities to investigate sophisticated quantum optical effects in a solid-state system. These include quantum interference, Rabi oscillations, as well as photon antibunching, and were previously only observable in isolated atoms or ions. In addition, QDs can be readily integrated into optical microcavities, making them attractive for a number of applications, particularly for quantum information processing and high efficiency quantum light sources. Recent successful demonstrations of resonant fluorescence of single quantum emitters have further open a new door toward coherently control of solid-state quantum emitters in microcavities. This talk will focus on these new recent developments.

Biography: Chih-Kang Shih received a Ph.D. in applied physics from Stanford Electronics Lab of Stanford University in 1988. After one-year postdoctoral research at IBM T.J. Watson Research Center at Yorktown Heights of NY, he joined the University of Texas at Austin. He worked there as an Associate Professor of Physics from 1990 to 2001 (Trull Centennial Fellow from 1992 to 1994) and Professor of Physics from 2002 to 2004, respectively. Since 2004, he has been the Jane and Roland Blumberg Centennial Professor of Physics at theUniversity of Texas at Austin. He is a Fellow of the American Physical Society, the American Vacuum Society, and Materials Research Society; meanwhile he is a recipient of Distinguished Alumni Award from National Tsing-Hwa University in Taiwan. His current research interests involves structural, electronic and optical properties of semiconductor nanostructures, quantum information processing and coherence/ decoherence in semiconductor quantum dots, quantum engineering of metallic nanostructures, collective and quasiparticle properties in nanostructues, nanomechanical properties of soft condensed matter systems. He is internationally renowned for his pioneering works in surface physics and quantum information processing. For example, he and his collaborators were among the first to demonstrate the novel electronic growth mode of atomically smooth metal overlayers onto semiconductor substrates and it was one of the first groups reporting Rabi oscillation and quantum interference phenomena in these solid-state nanoscale systems.
