Exact Optical Frequencies on Demand

06-11-18

Professor Kerry J. Vahala and colleagues have developed a prototype of a miniature device that synthesizes frequencies on demand with about 1 Hertz accuracy. It combines a frequency comb developed at the National Institute of Standards and Technology (NIST) with a "fine-toothed" frequency comb developed at Caltech. To create the finely spaced comb teeth, the Caltech resonator must be about 100 times larger than the NIST device. Its larger size can potentially make this comb very power hungry. "Too much power in a small space can damage any electronics to which the resonator is connected," Professor Vahala says. "Also, in the future, these synthesizer devices could operate on battery power in smartphone-sized devices where they cannot draw much power." But the Caltech comb can generate specific frequencies with minimal amounts of power. [Caltech story]

For the Record

06-05-18

CMS alumnus Ramruthwick “Ruthwick” Pathireddy (BS ’17) is described as curious, ambitious, and rigorous. “When people talk about Caltech, they think of students studying really hard,” Ruthwick says. “While we do study hard, there’s more to it than that. I don’t think people realize the social opportunities that are available here, how enriching the activities are, and how close the entire undergraduate community is. It’s really like a family.” [Breakthrough story]

Building the Starshot Sail

06-04-18

Professor Harry A. Atwater, Jr. is an advisor to a multi-disciplinary $100-million project aimed at designing a spacecraft that can be launched to planets surrounding other stars and reach them within our lifetime. The Breakthrough Starshot Program has three big technical challenges: The first is to build the so-called photon engine, the laser that's capable of propelling the sail; the second is to design the sail itself; and the third is to design the payload, which will be a tiny spacecraft capable of taking images and spectral data and then beaming them back to the earth. Professor Atwater’s role is to help the program define pathways to making a viable lightsail that's compatible with the other objectives of the whole program. [Caltech story]

Looking Back on the Birth of the Information Age

05-29-18

Carver Mead, one of the fathers of modern computing, combines memoir and instruction in new video series. "My feeling is that these days, if it's not on the web, it doesn't exist," Professor Mead says of the decision to launch the new video channel. The video series is available for free on YouTube, and aims to provide a better understanding of the birth and evolution of modern computing, as told by one of its key participants and witnesses.

2018 Caltech Distinguished Alumni

05-24-18

Caltech has recognized three Engineering and Applied Science (EAS) graduates with the Distinguished Alumni Award, the highest honor regularly bestowed by the Institute. Gary Demos (BS '71, Engineering and Applied Science), Gary A. Flandro (MS '60, PhD '67, Aeronautics), and Ronald H. Willens (BS '53 Physics, MS '54 Mechanical Engineering, PhD '61 Engineering Science). Demos was recognized “for his pioneering achievement in the development of computer-generated images (CGI) for use in motion pictures, and in digital film scanning and recording.” Flandro was recognized for “his seminal contributions to the design and engineering of multi-outer-planet missions, including the Grand Tour, the course set for the epic explorations of the Voyager spacecraft.” Willens was honored for “his innovative and revolutionary contributions to advanced internet connectivity and telecommunications. He pioneered the Remote Authentication Dial-in User Service (RADIUS) as an access server authentication and accounting protocol, which was adapted by the Internet Engineering Task Force (IETF) standards.” [Caltech story]
