Laser Design Expert to Receive 2008 IEEE Sarnoff Award

Nov 2008
JamesColeman.jpgThe Institute of Electrical and Electronics Engineers Inc. (IEEE) has named James J. Coleman as recipient of the 2008 IEEE David Sarnoff Award for his contributions to the development of reliable strained-layer lasers used to improve the performance of fiber optic telecommunications systems. Coleman's most notable contribution to the field of optoelectronics is his work on strained-layer quantum-well lasers. Coleman and his group proved that both performance and reliability were higher using strained-layers in lasers. This discovery enabled development of the 980-nm pump laser used in a variety of technologies, particularly as a pump laser for erbium-doped optical amplifiers used by telecommunication companies to increase the capacity of networks without having to lay additional fiber optic cable. An IEEE Fellow, Coleman began his career at the U of I as a research associate, and then moved on to technical staff positions at both Bell Laboratories and Rockwell International. While at Rockwell, Coleman contributed to the development of the metalorganic chemical vapor deposition (MOCVD) growth method used in semiconductor and photonic devices found in commercial compact disc and high-power lasers for optical storage and medical applications. In 1982, he returned to the university as professor of electrical and computer engineering. Coleman has co-authored 375 journal publications and holds seven patents. He is a Fellow of the American Physical Society, American Association for the Advancement of Science and Optical Society of America. The IEEE David Sarnoff Award, sponsored by Sarnoff Corp., will be presented to Coleman Nov. 10 at the LEOS Annual Meeting in Newport Beach, Calif.


GLOSSARY
light
Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
optoelectronics
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
