The New Blauvelt Fellowship Supports Graduate Students in Charting Their Own Paths


The New Blauvelt Fellowship gives graduate students in applied physics and materials science freedom to experiment and explore. As the digital revolution took root in the 1980s, television was still operating in an analog world, where signal interference caused static, snow, and ghosting. We owe the high-quality images we enjoy today in part to Henry “Hank” Blauvelt (PhD ΚΌ83), whose work in fiber optic communications helped usher in the digital television era. Blauvelt, in turn, credits Caltech for giving him the skills and the network to make these contributions. [Caltech story]

Professor Yariv Elected As Honorary Member of The Optical Society


Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Electrical Engineering, has been elected as a 2017 Honorary Member of The Optical Society. He was elected for pioneering scientific and engineering contributions to photonics and quantum electronics that have profoundly impacted lightwave communications and the field of optics as a whole. Professor Yariv joins a very select and highly distinguished group of Honorary Members which include George E. Hale in 1916 and R.A. Millikan in 1950 from Caltech. [List of Honorary Members]

Professor Yariv Elected to National Academy of Inventors


Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, has been named fellow of the National Academy of Inventors (NAI). His research has focused on creating the mathematical tools and building blocks underpinning guided wave optics, the backbone of today's optoelectronic technologies. This endeavor led to the proposal and demonstration of the distributed feedback laser and started the field of optoelectronic integrated circuits. Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."

A New Laser for a Faster Internet


Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, and his group have developed a new laser that has the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet. "What became the prime motivator for our project was that the present-day laser designs have an internal architecture which is unfavorable for high spectral-purity operation. This is because they allow a large and theoretically unavoidable optical noise to comingle with the coherent laser and thus degrade its spectral purity," Professor Yariv describes. [Caltech Release]

Former Caltech Postdoc Receives Israel Prize


Mordechai (Moti) Segev, a former postdoctoral fellow in Professor Amnon Yariv's group, will be receiving the Israel Prize for Physics and Chemistry. Dr. Segev is receiving the prize for ground-breaking research in the field of optics and lasers. "I am naturally proud of the achievements of former students and postdocs who started their scientific career in my group," says Professor Yariv. "Among this group Moti has become, in the relatively short time since leaving us, one the best known and influential scientists in the world in the field of quantum electronics and its amazing offspring of nonlinear optics. I am looking forward to a continuing stream of intellectual and experimental innovation flowing from him and his research group at the Technion."

Amnon Yariv Awarded National Medal of Science


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.
