Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Amnon YarivElectrical Engineering, and his group have developed a new laser that has the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet. "What became the prime motivator for our project was that the present-day laser designs have an internal architecture which is unfavorable for high spectral-purity operation. This is because they allow a large and theoretically unavoidable optical noise to comingle with the coherent laser and thus degrade its spectral purity," Professor Yariv describes.

William Bridges, Carl F Braun Professor of William BridgesEngineering, Emeritus, discovered and patented the Argon ion laser on February 14, 1964, while at Hughes Research Laboratories. Today noble gas (argon, krypton, xenon) lasers are used in a variety of applications including DNA sequencers, cell sorters, eye surgery, and laser light shows. Professor Bridges' research work with lasers involved an airborne night reconnaissance system (AN/AVD-3), space communications systems, early high power laser weapons (the carbon dioxide gas dynamic laser), and hydrogen maser clocks for the global positioning system. He also holds the patent for the Ionized Noble Gas Laser. [Oral History of Prof. Bridges] 02.21.14

Venkat Chandrasekaran, Assistant Professor of Computing and Mathematical Sciences and Electrical Engineering, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his 5-year project, "Computational and Statistical Tradeoffs in Massive Data Analysis". The CAREER program is NSF's most prestigious awards for junior faculty members. The level and 5-year duration of the awards are designed to enable awardees to develop careers as outstanding teacher-scholars. Awardees are chosen because they exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations. 01.27.14

Dr. Sander Weinreb, Faculty Associate in Sander WeinrebElectrical Engineering, has received the American Astronomical Society (AAS) Joseph Weber Award for Astronomical Instrumentation. He was recognized for his seminal innovations that have helped define modern-day radio astronomy, including digital autocorrelation spectrometers and cryogenic low-noise amplifiers and mixers. Dr. Weinreb is also cited for providing outstanding leadership for radio-astronomy instrumentation, especially for the electronics system of the Very Large Array. His innovations have been utilized in all radio observatories and have enabled countless astronomical discoveries. [Past Recipients] 1.21.14

A recent New York Times' Science article Carver Meadabout a new computing approach based on the nervous system mentions Carver Mead, Gordon and Betty Moore Professor of Engineering and Applied Science, Emeritus. The new processors used in this approach consist of electronic components that can be connected by wires that mimic biological synapses. Because they are based on large groups of neuron-like elements, they are known as neuromorphic processors, a term credited to Carver Mead, who pioneered the concept in the late 1980s.
