Summary:
The primary emphasis of Dr. Lichtenberger's research is the investigation of materials, processing technologies and devices for superconducting circuits. The driving force of this research is the need for ultra-low-noise heterodyne receivers at millimeter and submillimeter wavelengths. Of particular emphasis is the investigation and development, with NRAO, of complex integrated SIS mixers for the new International Atacama Large Millimeter Array (ALMA). We have also recently been investigating superconducting nano sized hot electron bolometers for THz frequencies integrated with laser machined waveguide and quasi-optic components. With both of these structures we are also developing beam lead technologies for quartz and ~micron thick frameless Si chips for THz integrated arrays.

Background:
Arthur Lichtenberger received the B.A. degree in Physics from Amherst College in 1980, and the M.S. and Ph.D. degrees in Electrical Engineering in 1985 and 1987 respectively from the University of Virginia. Dr Lichtenberger has served on the faculty since 1987 and is presently Director of the UNIVERSITY of VIRGINIA MICROFABRICATION LABORATORY UVML. He has published over 55 technical articles and is a member of the International Union of Radio Science, Eta Kappa Nu, Sigma Xi, and Tau Beta Pi.
