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]

'Comb on a Chip' Powers New Atomic Clock Design

07-22-14

Scott Diddams who was a 2012 Caltech Moore Distinguished Scholar and is a Project Lead at National Institute of Standards and Technology (NIST) and colleagues including Professor Kerry Vahala have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb, or a microcomb. The microcomb clock is the first demonstration of all-optical control of the microcomb, and its accurate conversion of optical frequencies to lower microwave frequencies. Caltech researchers made the 2-millimeter-wide silica disk that generates the frequency comb for the new clock. [NIST Press Release] [Learn More]

Future Electronics May Depend on Lasers, Not Quartz

07-18-14

Kerry Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics as well as the Executive Officer for APhMS, and colleagues have developed a method to stabilize microwave signals in the range of gigahertz, or billions of cycles per second—using a pair of laser beams as the reference, in lieu of a quartz crystal. "There are always tradeoffs between the highest performance, the smallest size, and the best ease of integration. But even in this first demonstration, these optical oscillators have many advantages; they are on par with, and in some cases even better than, what is available with widespread electronic technology," Vahala says.

Tricking the Uncertainty Principle

05-15-14

Keith Schwab, Professor of Applied Physics and the Fletcher Jones Foundation Co-Director of the Kavli Nanoscience Institute, and colleagues have found a way to make measurements that go beyond the limits imposed by quantum physics. "Our mechanical device is a tiny square of aluminum—only 40 microns long, or about the diameter of a hair. We think of quantum mechanics as a good description for the behaviors of atoms and electrons and protons and all of that, but normally you don't think of these sorts of quantum effects manifesting themselves on somewhat macroscopic objects," Schwab says. "This is a physical manifestation of the uncertainty principle, seen in single photons impacting a somewhat macroscopic thing." [Caltech Release]

Professor Greer Named One of Most Creative People in 2014

05-13-14

Julia R. Greer, Professor of Materials Science and Mechanics, has been named one of Fast Company's Most Creative People in 2014. "What if you could fabricate nanotrusses--materials made up of tiny, intricate geometric structures linked together--in a way that might resemble, say, the webwork of the Eiffel Tower?" describes Professor Greer.
