Clean-Energy Research Accelerates

10-22-12

Caltech clean-energy research is accelerating thanks to the renovation of the Earle M. Jorgensen Laboratory. Transformed into a cutting-edge facility for energy science, the lab unites two powerhouse programs: the Resnick Sustainability Institute and the Joint Center for Artificial Photosynthesis (JCAP). "Our researchers are working with Caltech's chemists and chemical engineers to challenge the status quo and translate scientific discovery into clean-energy innovations that will directly benefit society for generations to come," says Chair Ares Rosakis.

Seeing Inside Tissue

06-26-12

Changhuei Yang, Professor of Electrical Engineering and Bioengineering, and colleagues Ying Min Wang and Benjamin Judkewitz have developed a new method to focus light inside biological tissue. "It enables the possibilities of doing incision-less surgery," says Professor Yang. "By generating a tight laser-focus spot deep in tissue, we can potentially use that as a laser scalpel that leaves the skin unharmed." [Caltech Press Release]

Calculating the Capacity of a Network

06-04-12

Michelle Effros, Professor of Electrical Engineering, and information theorist colleagues have begun to tackle the difficult problem of calculating capacities for large communication networks such as the internet and mobile phone networks. In two recent publications, they introduce techniques useful for improving the performance of current communication networks and for designing the networks of the future. By demonstrating where current technology falls short of what's possible, these techniques provide a new tool for strategically guiding research and development. [Read the Publications]

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]

Sander Weinreb Awarded the Karl G. Jansky Lectureship

06-16-11

Dr. Sander Weinreb, Faculty Associate in Electrical Engineering, has been awarded the Karl G. Jansky Lectureship. This is an honor established to recognize outstanding contributions to the advancement of radio astronomy. Weinreb’s development of the first autocorrelation spectrometer and the detection of the first interstellar molecule at radio wavelengths revolutionized astronomy. He has been a leader in the technological development of cm and mm astronomy throughout his career.

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.
