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.

Oskar Painter and Kerry Vahala Trap Light and Sound Vibrations Together in Nanocrystal

10-26-09

Oskar Painter, Associate Professor of Applied Physics, and Kerry J. Vahala Ted and Ginger Jenkins Professor of Information Science and Technology and Professor of Applied Physics; Director, The Lee Center for Advanced Networking have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. "This novel approach... exemplifies the forward-thinking work being done by the Engineering and Applied Science division," says Ares Rosakis, Chair and Theodore von Kármán Professor of Aeronautics and Mechanical Engineering at Caltech.

Kerry Vahala Wins Alexander Von Humboldt Research Award

09-29-08

Kerry Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Professor of Applied Physics, has won an Alexander Von Humboldt Research Award. The Humboldt award recognizes academics whose fundamental discoveries, new theories, or insights have had a significant impact on their own discipline and who are expected to continue producing cutting-edge achievements. Vahala has also been awarded and the IEEE David Sarnoff Award for exceptional contributions to electronics, and in particular, "for seminal contributions to improved dynamics of quantum well semiconductor lasers."
