Nano-mechanics of Carbon Nanotube Research Wins Art Competition

08-22-11

Siddhartha (Sid) Pathak, a W. M. Keck Institute for Space Studies (KISS) Postdoctoral Fellow in Material Science, has received the first prize in the NanoArt 2011 International Competition. The inspiration for Dr. Pathak's entry entitled "In-situ SEM deformation of CNT micro-pillars" is his research on nano-mechanics of carbon nanotubes.  As a KISS postdoc Dr. Pathak is working with  Professor Julia Greer on mechanical testing of carbon nanotubes at submicron length scales, with a particular emphasis towards space applications.

Engineers Solve Longstanding Problem in Photonic Chip Technology

08-04-11

Liang Feng, a Postdoctoral Scholar in Electrical Engineering who works with Professor Axel Scherer, has designed a new type of optical waveguide - a 0.8-micron-wide silicon device. The waveguide allows light to go in one direction but changes the mode of the light when it travels in the opposite direction. This new technique to isolate light signals on a silicon chip, solves a longstanding problem in engineering photonic chips. [Caltech Press Release]

How an Idea Becomes a Business

03-29-11

Students in Ken Pickar's course Entrepreneurial Development (E 102) have the opportunity to identify a technology currently under study at Caltech and develop a business plan for it. The ideas used by the students this year included a solid-state memory technology developed by Jehoshua (Shuki) Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering. In this business plan the students proposed targeting Netflix and other high-volume streaming content providers. Another team pinpointed a new market for the vertical wind turbines of John O. Dabiri, Professor of Aeronautics and Bioengineering. A third team pitched a noninvasive method for breaking up arterial plaques using the concentrated-acoustic-pulse technology developed by Chiara Daraio, Professor of Aeronautics and Applied Physics.

Amnon Yariv Awarded National Medal of Science

10-15-10

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, has received one of the highest honors bestowed by the United States government on scientists, and engineers. He is a recipient of the National Medal of Science. Professor Yariv's research group has pioneered the field of optoelectronics. Many innovations such as distributed Feedback (DFB) Semiconductor Lasers, Integrated Optoelectronic Circuits, Optical Phase Conjugation, External Cavity Tunable Semiconductor Lasers, Quantum Well Infrared Photodetectors (QWIP's), and all-fiber add/drop filters have found their beginnings in his research group. Currently, his group’s research aims at developing the new technologies that will be mandated by the seemingly endless appetite for optical bandwidth. Specifically, they are working at extending, to the field of laser optics, some key ideas that form the foundation of the microwaves and the radio frequencies fields.
