Former Caltech Postdoc Receives Israel Prize

01-15-14

Mordechai (Moti) Segev, a former postdoctoral fellow in Professor Amnon Yariv's group, will be receiving the Israel Prize for Physics and Chemistry. Dr. Segev is receiving the prize for ground-breaking research in the field of optics and lasers. "I am naturally proud of the achievements of former students and postdocs who started their scientific career in my group," says Professor Yariv. "Among this group Moti has become, in the relatively short time since leaving us, one the best known and influential scientists in the world in the field of quantum electronics and its amazing offspring of nonlinear optics. I am looking forward to a continuing stream of intellectual and experimental innovation flowing from him and his research group at the Technion."

Using Space Wisely

01-09-14

The Winter 2013 issue of Engineering & Science features Professor Sergio Pellegrino's Space Structures Laboratory in the Guggenheim building. “The goal for much of my work,” says Pellegrino, “is to make simpler and cheaper spacecraft. I want to use clever structural engineering to make access to space more affordable.” The article also describes him and his team's work on the AAReST project (Autonomous Assembly of a Reconfigurable Space Telescope) as well as applications of his work to solar concentrators.

Jorgensen Laboratory Wins SCDF Science & Technology Award

12-13-13

The Earle M. Jorgensen Laboratory has won the Science and Technology Award from the Southern California Development Forum (SCDF). The building was rededicated in October of 2012 and stands as a symbol of Caltech's lasting commitment to sustainability research. From the early renderings of Fall 2010, Jorgensen was depicted as an innovative space -with communal areas to support collaboration, ample meeting spaces, and state of the art laboratories.

Spirals of Light May Lead to Better Electronics

09-25-13

Kerry J. Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics as well as Executive Officer for Applied Physics and Materials Science, and colleagues have created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end electronics and stabilize the signals of high-quality lasers. They were able to stabilize the light's frequency by developing a silica glass chip resonator with a specially designed path for the photons in the shape of what is called an Archimedean spiral.

Made-to-Order Materials

09-06-13

Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues have created nanostructured, hollow ceramic scaffolds, and have found that the small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air. The general fabrication technique the researchers have developed could be used to produce lightweight, mechanically robust small-scale components such as batteries, interfaces, catalysts, and implantable biomedical devices.

Solar Decathlon 2013 Construction is Under Way

09-03-13

Last year a group of students in an engineering project course called Introduction to Multidisciplinary Systems Engineering, taught by Professor Melany Hunt, began planning for the Dynamic Augmented Living Environment (DALE), a joint SCI-Arc/Caltech entry in the 2013 Solar Decathlon competition. This type of multidisciplinary and collaborative experience is important for Caltech students, notes Hunt. "Engineering students need experiences in which they design, create, build, and test," she says. "They also should have opportunities in which they work as part of a team. Most engineering projects require multiple perspectives with input coming from a range of individuals with different expertise and vision." [Caltech Release] [LA Times Article]

Producing Squeezed Light Using a Silicon Micromechanical System

08-07-13

Oskar J. Painter, Professor of Applied Physics, and colleagues have produced squeezed light using a silicon micromechanical system. "This system should enable a new set of precision microsensors capable of beating standard limits set by quantum mechanics," says Professor Painter. "Our experiment brings together, in a tiny microchip package, many aspects of work that has been done in quantum optics and precision measurement over the last 40 years." [Caltech Release]

Creating Indestructible Self-Healing Circuits

03-11-13

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and colleagues have built electronic chips that repair themselves. The team has demonstrated this self-healing capability in tiny power amplifiers. The amplifiers are so small, in fact, that 76 of the chips—including everything they need to self-heal—could fit on a single penny. In perhaps the most dramatic of their experiments, the team destroyed various parts of their chips by zapping them multiple times with a high-power laser, and then observed as the chips automatically developed a work-around in less than a second.
