Abstract:

Microplasma devices are a new generation of micro-optical 
sources and detectors that have been fabricated in 
semiconductors, ceramics, and metal/dielectric/metal 
structures.  Capable of producing photons from the infrared 
spectral region to the vacuum ultraviolet, these devices are 
well suited for integration with micro-optoelectronic, 
fluidic, and mechanical systems.  Photodetection in the 
ultraviolet, visible, and near infrared has also been 
observed with microdischarge devices having pyramidal Si 
photocathodes.  Sensitivities more than an order of magnitude 
larger than that available from Si avalanche photodiodes are 
observed.  The optical and electrical characteristics of 
devices as small as ~10 microns in diameter and arrays with 
~1000 pixels at packing densities >10000 cm-2 will be 
discussed. 


Biography:

J. Gary Eden, received his Ph.D. from the University of 
Illinois (1976), was a National Research Council Post-
Doctoral Research Associate at the U.S. Naval Research 
Laboratory (Washington, DC) and then was appointed a research 
physicist in the Laser Physics Branch.  He joined the 
University of Illinois faculty in 1979 where he has been 
engaged in research in molecular and ultrafast laser 
spectroscopy, the discovery and development of visible and 
ultraviolet lasers, and microplasma devices.  He is a Fellow 
of the IEEE, the Optical Society of America and the American 
Physical Society, Past Editor-in-Chief of the IEEE "Journal 
of Quantum Electronics," and has served as Associate Vice-
Chancellor for Research, Assistant Dean of the College of 
Engineering, and Associate Dean of the Graduate College.  Dr. 
Eden was the James F. Towey Scholar at the University of 
Illinois from 1996 through 1999 and, in 1998, served as 
President of the IEEE Lasers and Electro-Optics Society 
(LEOS).  He is Professor in the Department of Electrical and 
Computer Engineering, as well as a Research Professor in the 
Coordinated Science Laboratory and the Microelectronics 
Laboratory.
