Bending the Light with a Tiny Chip

03-10-14

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and colleagues have developed a new light-bending silicon chip that acts as a lens-free projector--and could one day end up in your cell phone. They were able to bypass traditional optics by manipulating the coherence of light—a property that allows the researchers to "bend" the light waves on the surface of the chip without lenses or the use of any mechanical movement.

A New Laser for a Faster Internet

02-26-14

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical 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. [Caltech Release]

ENGenious Wins Silver!

02-19-14

The 2013 issue of ENGenious has won a silver award from the Council for Advancement and Support of Education (CASE) District VII in the Awards of Excellence category of Annual Magazines. The award is given by the CASE District VII Board of Directors and the Awards of Excellence Committee to "superior magazines published once a year." First published in 2001, ENGenious is a publication for alumni and friends of the Caltech Division of Engineering and Applied Science (EAS). The goal of the publication is to highlight the contributions of the EAS faculty, students, and alumni in research, education, and industry. [ENGenious]

Celebrating 50 Years of the Argon Ion Laser

02-14-14

William Bridges, Carl F Braun Professor of Engineering, 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]

Professor Chandrasekaran Receives NSF CAREER Award

01-24-14

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.

Brainlike Computers, Learning From Experience

01-06-14

A recent New York Times' Science article about 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.

Caltech Names Ninth President

10-24-13

Thomas F. Rosenbaum has been named the ninth president of Caltech. Dr. Rosenbaum, is currently the John T. Wilson Distinguished Service Professor of Physics at the University of Chicago, where he has served as the university's provost for the past seven years. Also joining Caltech and the EAS Division will be Dr. Rosenbaum's spouse, Katherine T. Faber, the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern University. Professor Faber's research focuses on understanding stress fractures in ceramics, as well as on the fabrication of ceramic materials with controlled porosity, which are important as thermal and environmental barrier coatings for engine components. She is also the codirector of the Northwestern University-Art Institute of Chicago Center for Scientific Studies in the Arts (NU-ACCESS), which employs advanced materials science techniques for art history and restoration.
