Spinning the Light: The World's Smallest Optical Gyroscope


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]

Illuminating New Possibilities


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]

President Rosenbaum Highlights Postdocs as "Unsung Heroes"


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


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]

EE students Win $100K Qualcomm Innovation Fellowships


Graduate students Ehsan Abbasi and Fariborz Salehi, working with Professor Babak Hassibi, have won a 2018 Qualcomm Innovation Fellowship. They proposed a new algorithm for data recovery in Massive MIMO systems, which has a near optimal performance while being computationally efficient. Massive MIMO is the key enabler in the upcoming 5G data networks which promise considerably higher data rates in future generations of wireless networks. This year there were 174 submissions to Qualcomm for the fellowship and only 8 winning teams were chosen. Each winning team will be awarded a $100K fellowship and receive mentorship from Qualcomm engineers. [List of winners]

Looking Back on the Birth of the Information Age


Carver Mead, one of the fathers of modern computing, combines memoir and instruction in new video series. "My feeling is that these days, if it's not on the web, it doesn't exist," Professor Mead says of the decision to launch the new video channel. The video series is available for free on YouTube, and aims to provide a better understanding of the birth and evolution of modern computing, as told by one of its key participants and witnesses.
