Professor Atwater Receives Julius Springer Prize for Applied Physics

08-13-14

Harry A. Atwater, Jr., Howard Hughes Professor of Applied Physics and Materials Science as well as Director of the Resnick Sustainability Institute, has received the Julius Springer Prize for Applied Physics for pioneering achievements in plasmonics and novel nanophotonic routes to ultrahigh-efficiency solar energy conversion. Professor Atwater’s scientific interests have two themes: plasmonics and optical metamaterials as well as photovoltaics and solar energy conversion. He is an early pioneer in nanophotonics and plasmonics, giving the name to the field of plasmonics in 2001. The Julius Springer Prize is awarded annually to scientists who have made an outstanding and innovative contribution to the field of applied physics. [Caltech Release] [Springer release]

Resonate Awards Honor Global Champions of Sustainability

05-19-14

The Resnick Sustainability Institute has announced five innovators in the fields of energy science and sustainability as the inaugural winners of the Resonate Awards. "We are committed to finding scalable long-term solutions to some of the biggest energy and environmental problems facing the world today," says Harry Atwater, the Howard Hughes Professor of Applied Physics and Materials Science and director of the Resnick Sustainability Institute. "We started the Resonate Awards because we realized that there is an urgent need to recognize and promote the advances of sustainability innovators." [2014 Resonate Award Winners] [Caltech Release]

Quantum Photon Properties Revealed in Another Particle—the Plasmon

04-03-14

Harry A. Atwater, Jr., Howard Hughes Professor of Applied Physics and Materials Science as well as Director of the Resnick Sustainability Institute, and colleagues’ experiments have confirmed that two indistinguishable photons can be converted into two indistinguishable surface plasmons that, like photons, display quantum interference. This finding could be important for the development of quantum computing, says Atwater. "Remarkably, plasmons are coherent enough to exhibit quantum interference in waveguides," he says. "These plasmon waveguides can be integrated in compact chip-based devices and circuits, which may one day enable computation and measurement schemes based on quantum interference." [Caltech Release]

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]

Professor Gerald Whitham Passes Away

02-12-14

Gerald B. Whitham, Charles Lee Powell Professor of Applied Mathematics, Emeritus, passed away on Sunday, January 26, 2014 at the age of 86. Professor Whitham was a pioneer in the area of nonlinear waves. His research focused on fluid dynamics and the study of wave phenomena, including sonic booms, supersonic flow and shock-wave dynamics, and ocean waves. He was also instrumental in setting up Caltech's applied mathematics program in 1962, which is now part of the Department of Computing and Mathematical Science .

Nanoscale Materials and Big Solar Energy

02-06-14

As a high school student during the oil crisis of the 1970s, Professor Harry Atwater recognized firsthand the impact of energy supply issues. Inspired to contribute to renewable energies, his research at Caltech today works to develop better thin-film photovoltaics—cheaper, lighter, more efficient alternatives to the bulky cells now used in solar panels.
