Partners In Innovation

11-13-18

Ten years ago, Caltech and City of Hope forged a partnership that combined what each institute was best at—engineering and medicine, respectively—with the goal of developing new biomedical technologies. At this year’s partnership celebration two projects were highlighted one involving Professor Yu-Chong Tai’s work on tracking tumors and the other building on Professor Morteza Gharib’s device to measure heart health.

"Folded" Optical Devices Manipulate Light in a New Way

10-30-18

Andrei Faraon, Professor of Applied Physics, and colleagues have introduced a technology called "folded metasurface optics," which is a way of printing multiple types of metasurfaces onto either side of a substrate, like glass. In this way, the substrate itself becomes the propagation space for the light. As a proof of concept, the team used the technique to build a spectrometer. Such compact spectrometers have a variety of possible uses, including as a noninvasive blood-glucose measuring system. [Caltech story]

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]

Caltech Startup Aims to Make Solar Panels More Efficient

10-18-18

Translational technology developed in Professor Harry A. Atwater’s laboratory seeks to improve the efficiency of solar panels by tweaking the architecture of the metal-grid layout of individual cells. The new startup company—ETC Solar, LLC—which is marketing the technology, took first place at the DOE's 2018 Cleantech University Prize national collegiate business plan competition in Houston. "To have been selected as a winner is a huge point of validation for the concept, both the innovation and also the impact," says Professor Atwater, who is also a co-founder of ETC Solar along with Thomas Russell, and Rebecca Saive. "It has helped us to make contacts with potential industrial partners and private equity investors," [Caltech story]

Illuminating New Possibilities

10-10-18

Alireza Marandi, Assistant Professor of Electrical Engineering, explores how nonlinear photonics, a field of optics, enables a broad range of previously less-explored opportunities for using lasers and light detectors for a variety of purposes, including molecular sensing and computing. One possible application of his work is in breath analysis. He describes, “ there's a lot of useful information about your health contained in your breath, but it is difficult to analyze because the concentrations are so low. To overcome that, you could analyze the spectra of exhaled breath using lasers, searching for the spectral "fingerprints," or signatures, that reveal the presence of those compounds.” [Interview with Professor Marandi]

Caltech Awarded Federal Funding for Quantum Research

09-25-18

EAS Professors were among a small group of Caltech scientists and engineering who have won federal grants for research in quantum computing, and quantum networks. Professor Nadj-Perge (lead PI) along with co-PIs Professors Marco Bernardi and Andrei Faraon as well as co-investigator Professor Julia Greer have received funding for the program ”Quantum States in Layered Heterostructures Controlled by Electrostatic Fields and Strain," which is administered within the U.S. Department of Energy's Basic Energy Sciences division. Professor Austin Minnich is a co-PI of the program, "Quantum simulation of materials and molecules using quantum computation," which is part of the National Science Foundation's Research Advanced by Interdisciplinary Science and Engineering (RAISE)-Transformational Advances in Quantum Systems (TAQS) effort.

President Rosenbaum Highlights Postdocs as "Unsung Heroes"

09-24-18

In a letter to the Caltech community during National Postdoc Appreciation Week, the Caltech President emphasizes the role this key group plays at the Institute. He stated, “Caltech's mission of world-leading research and education depends crucially on our postdoctoral scholars. Although their time at Caltech may be short, they quickly become vital parts of the Institute's intellectual fabric.” [President’s Letter] [EAS Postdoc Resource Page]

The Possibilities are Mote and Remote

08-17-18

Professor Azita Emami’s work in high-speed data communications has led to a breakthrough that could spare millions of people the need to prick themselves with needles. As she engineers a more connected world, she also is working to make it a healthier one. Professor Emami doesn’t draw a line between the different endeavors. “Electronic systems for cell phones and computers are very, very advanced,” she explains. “So why not take the knowledge we have gained developing those technologies and find ways to apply it toward solutions in medicine?” [Breakthrough story]

Engineers Taught a Drone to Herd Birds Away From Airports

08-08-18

Soon-Jo Chung, Associate Professor of Aerospace and Bren Scholar; Jet Propulsion Laboratory Research Scientist, and colleagues have developed a new control algorithm that enables a single drone to herd an entire flock of birds away from the airspace of an airport. The effectiveness of the algorithm is only limited by the number and size of the incoming birds, Professor Chung says, adding that the team plans to explore ways to scale the project up for multiple drones dealing with multiple flocks.[Caltech story]
