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]

Professors Barr and Schröder Elected to ACM SIGGRAPH Academy

10-05-18

Alan Barr, Professor of Computer Science, and Peter Schröder, Shaler Arthur Hanisch Professor of Computer Science and Applied and Computational Mathematics, have been elected to the first class of the ACM SIGGRAPH Academy. Professor Barr was selected for his contributions to graphics, primarily for extending computer graphics shape modeling to include physically based and teleological modeling. Professor Schröder was recognized for his pioneering work in geometry processing and multiresolution modeling. The ACM SIGGRAPH Academy is an honorary group of individuals who have made substantial contributions to the field of computer graphics and interactive techniques. These are principal leaders of the field, whose efforts have shaped the disciplines and/or industry, and led the research and/or innovation in computer graphics and interactive techniques.

Caltech and Amazon Web Services Launch Collaboration

09-26-18

Researchers from Caltech and Amazon Web Services (AWS) are collaborating in Pasadena to foster a relationship that could change the landscape of artificial intelligence (AI) research in Southern California. “Our graduate programs train extraordinarily talented future researchers, who mostly leave Pasadena after completing their PhD." An industry research center located nearby, however, can help retain talent locally, says Professor Pietro Perona one of the architects of the new collaboration. "Together, we can build a critical mass of machine-learning and AI researchers right here in Pasadena.” Primarily affiliated with Caltech via the CMS Department of the EAS Division, AWS will provide summer internships for Caltech students and students of other top universities, job opportunities for alumni, and the potential for collaborations between Caltech and AWS researchers. AWS is also contributing funding for Caltech projects and a pipeline for marketable research. AWS has already committed $2.5 million to Caltech for graduate student fellowships and cloud-computing credits in order to seed AI innovations. [Caltech story]

New Major and Minor in Information and Data Sciences

09-25-18

Starting in fall 2018, EAS will offer students a new undergraduate degree option in a field that is at the forefront of computer science: information and data sciences (IDS). Mathematics will form the backbone of the new option. Students in IDS will take core courses focusing on machine learning, information theory, probability, statistics, linear algebra, and signal processing. After that, they will have the opportunity to branch out with electives that cover applications of data sciences to science and engineering. Professor Adam Wierman hopes the creation of this new option will prepare both students and Caltech for the future. "It almost doesn't matter what you're interested in. If you want to make discoveries and be on the cutting edge of your field, you're going to need the skills to analyze and manipulate large collections of information," he says.  [Caltech story] [Degree option details]

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.
