　　Abstract: Vertical-cavity surface-emitting lasers (VCSELs) are a key enabling nanometer-scale photonics technology for optical fiber and free-space data communications, exaflop-per-second supercomputing, illumination, and sensing systems. I review my research group’s work on energy-efficient, gallium-arsenide-based VCSELs for short-reach and very-short-reach optical interconnects operating beyond 50 gigabits-per-second and below 50 femtojoules-per-bit, and our novel designs and recent results on the development of reduced-dimension-VCSELs envisioned for on-chip integration with silicon electronic and photonic systems.

　　Biography：J. A. Lott is a Professor in the Institute of Solid-State Physics at the Technische Universitat Berlin, Federal Republic of Germany. He was raised in Ewa Beach, Hawaii and Sunnyvale, California, United States of America (USA). He received the bachelor of science degree in electrical engineering and computer sciences from the University of California at Berkeley, USA in 1983 and the Ph.D. from the University of New Mexico, USA in 1993. He performed research at Sandia National Laboratories (US Department of Energy) in Albuquerque, New Mexico on quantum optoelectronic materials, devices, and systems from 1988-1993. While on sabbaticals he served as a visiting scientist at the NEC Optoelectronics Research Laboratories in Tsukuba, Japan in 1995, and at the Samsung Electronics Company in Suwon, Republic of Korea in 1996.
