'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.

Graduate Student Wins Young Stress Analyst Competition

07-17-14

Mechanical and civil engineering graduate student Ryan Hurley who works with Professor José Andrade has won the BSSM (British Society for Strain Measurement) Young Stress Analyst Competition at the 16th International Conference on Experimental Mechanics (ICEM.16). The competition is an annual competition that is intended to encourage and reward young practitioners in the field of experimental mechanics. Ryan was among six finalists representing universities in Belgium, Poland, France, and the USA, who were selected from 34 applications by a panel of experts. The finalists presented their work during the ICEM.16 conference and were judged by a panel of leading researchers. [YSA Competition Information]

120th Commencement Ceremony

06-13-14

Caltech's 120th Commencement Ceremony, held on Friday, June 13th, 2014, celebrated the accomplishments of 526 graduates. Awarded were 197 bachelor's degrees, 148 master's degrees, 2 engineer degrees, and 181 doctoral degrees. The graduates were addressed by the Pulitzer Prize-winning author Daniel Yergin, a leading authority on energy, international politics, and economics, and a recipient of the United States Energy Award. He inspired the graduate students with an address that encompassed six "lessons," including the advice to be curious and to act on one's convictions to change the world.
