Hrishika Basava Receives 2021 Henry Ford II Scholar Award

06-02-21

Hrishika Basava, advised by Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering; Co-Director, Space-Based Solar Power Project, is one of four recipients of the 2021 Henry Ford II Scholar Award. Hrishika is interested in many different aspects of electrical engineering, and specifically applications in robotics and aerospace. She does research in inverse design techniques for nanophotonics with Ali Hajimiri. Hrishika has also worked on the Caltech Racing electrical team and has done research on the explosion mechanism of supernovae at the Carnegie Observatories. At Caltech, she has particularly enjoyed taking hands-on project classes, as well as being a teaching assistant in electrical engineering courses. This summer, Hrishika will be interning at Nuro, a robotics company working on a self-driving car. After graduating she plans to pursue higher education and eventually work in the technology industry. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

Mohith Manohara Receives 2020 Henry Ford II Scholar Award

06-12-20

Electrical engineering student Mohith Manohara is a recipient of the 2020 Henry Ford II Scholar Award. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study. Mohith is currently a junior studying Electrical Engineering at Caltech. He does research on phased arrays with Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering; Co-Director, Space-Based Solar Power Project, and leads the electronics on the Caltech Robotics Team. This summer he will be doing an internship at a startup called Epirus, and afterwards he plans to pursue a PhD. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund.

Ali Hajimiri Wins Feynman Prize for Excellence in Teaching

02-14-19

Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering; Co-Director, Space-Based Solar Power Project, has won the 2019 Feynman Prize for Excellence in Teaching. Caltech's most prestigious teaching honor, the prize was established in 1993 "to honor annually a professor who demonstrates, in the broadest sense, unusual ability, creativity, and innovation in undergraduate and graduate classroom or laboratory teaching."

Spinning the Light: The World's Smallest Optical Gyroscope

10-25-18

Professor Ali Hajimiri and colleagues have developed a new optical gyroscope that is 500 times smaller than the current state-of-the-art device, yet they can detect phase shifts that are 30 times smaller than those systems. Their device achieves this improved performance by using a new technique called "reciprocal sensitivity enhancement." In this case, "reciprocal" means that it affects both beams of the light inside the gyroscope in the same way. [Caltech story]

2018 Watson Fellow

03-23-18

Electrical engineering senior Michelle Wang, working with Professor Ali Hajimiri and Postdoctoral Scholar Alex Pai, has been selected to receive the Thomas J. Watson Fellowship. She will spend a year abroad working on a series of projects related to the augmentation of humanity through machines. "Prosthetics for children need to be flexible, durable, and need to be able to grow with the child so that they don't have to be replaced constantly," she says. "But beyond that, we want to find ways to make them proud of their prosthetics. We don't just want to give them mobility but dignity." [Caltech story]

Ultra-Thin Camera Creates Images Without Lenses

06-22-17

Professor Ali Hajimiri and colleagues have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it manipulates incoming light to capture an image. "Here, like most other things in life, timing is everything. With our new system, you can selectively look in a desired direction and at a very small part of the picture in front of you at any given time, by controlling the timing with femto-second—quadrillionth of a second—precision," says Professor Hajimiri.

Professor Hajimiri Elected to National Academy of Inventors

12-16-15

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering; Executive Officer for Electrical Engineering; Director, Information Science and Technology, has been named fellow of the National Academy of Inventors (NAI). His research covers broad areas within high-speed and high-frequency electronics- and photonics-integrated circuits. This year, the Hajimiri group synthesized a 3-D camera—called a nanophotonic coherent imager—that provides the highest depth-measurement accuracy (similar to resolution) of any such nanophotonic 3-D imaging device. 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."

Space Solar Power Initiative

04-28-15

Caltech and Northrop Grumman Corporation have signed a $17.5 million sponsored research agreement for the development of the Space Solar Power Initiative (SSPI). The initiative will develop technologies in three areas: high-efficiency ultralight photovoltaics; ultralight deployable space structures; and phased array and power transmission. "The Space Solar Power Initiative brings together electrical engineers, applied physicists, and aerospace engineers in the type of profound interdisciplinary collaboration that is seamlessly enhanced at a small place like Caltech... We are working on extremely difficult problems that could eventually provide the world with new, and very cost-competitive technology for sustainable energy,” said EAS Chair Ares Rosakis.

Ali Hajimiri's New Camera Chip Provides Superfine 3-D Resolution

04-06-15

To make an exact copy of an object with a 3-D printer, you must first produce a high-resolution scan of the object with a 3-D camera that measures its height, width, and depth. The most sensitive systems generally are too large and expensive to be used in consumer applications. Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, has created a new device called a nanophotonic coherent imager (NCI) that is an inexpensive silicon chip less than a millimeter. The NCI provides the highest depth-measurement accuracy of any such nanophotonic 3-D imaging device. 3-D imaging may be a possible feature in future smartphones. [Caltech story]
