Teh-Hwa Wong

Teh-Hwa Wong received his B.S. and M.S. degrees in physics from the National Cheng Kung University in Taiwan and his Ph.D. degree from the University of Iowa in 1996. He is currently a contractor from Science Systems and Applications Inc. as a part of the Laser Remote Sensing Branch (LRSB) at NASA Langley Research Center, Hampton, VA. Dr. Wong has worked as a lecturer in the Department of Physics and Astronomy at the University of Iowa, as an Associate Research Scientist in the Department of Chemistry at Columbia University in New York City, and as a Research Investigator at the Department of Physics and Astronomy at the University of Iowa. He has also worked as a Research Scientist at the Applied Research Center at Old Dominion University, as part of the Department of Electrical Engineering and Computer Science at the University of Virginia, and at Laser and Plasma Technologies.

Dr. Wong’s current project is Infrared Signal Detection by Upconversion Technique. Below is the Abstract to one of Dr. Wong’s articles on the project.

Abstract: “We demonstrated up-conversion assisted detection of a 2.05 micrometer signal by using a bulk periodically poled Lithium niobate crystal. The 94% intrinsic up-conversion efficiency and 22.58% overall detection efficiency at pW level of 2.05 micrometers was achieved.”

He has appeared as an author or co-author on more than 30 scientific journals. Some of his works include: “Nanosecond Laser Pulse-Induced Electron Emissions From Multi-Wall Carbon Nanotube Film”, “Nanotechnology, Color Generation in Butterfly Wings and Fabrication of Such Structure”, and “Photodissociation of Acetaldehyde: The CH4 + CO Channel”.
