Integrating optics and electronics into systems such as fiber-optic data links has revolutionized how we transmit information. A second revolution awaits as researchers seek to develop chips in which individual atoms control the movement of light within the chip through optical "wires," and photons could replace electrons as the vehicle for performing computations. Andrei Faraon (BS '04), an assistant professor of applied physics and materials science in the Division of Engineering and Applied Science, presents a preview of this revolution at 8 p.m. on Wednesday, December 17, in Caltech's Beckman Auditorium. Admission is free.
The Einstein Papers Project at Caltech, the Princeton University Press, and the Hebrew University of Jerusalem have launched a digital edition of The Collected Papers of Albert Einstein. We recently spoke with Diana Kormos-Buchwald, director and general editor of the Einstein Papers Project, about the new, free resource.
Leaders of the Thirty Meter Telescope (TMT) project announced on Tuesday that the government of India has signed on as a full partner in the construction of what will be the world's largest ground-based telescope.
Solar panels convert visible light from the sun into electricity—but the sun's infrared light passes right through the panel's silicon material. Caltech researchers have come up with a method that may be able to harness that lost energy.
A team of researchers has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet. The geologists say that the ancient canyon—thousands of feet deep in places—effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast.
