professor Krishna Shenoy
December 2019

Professor Krishna Shenoy and neurosurgeon Jaime Henderson, MD lead a team of researchers that implanted multi-electrode arrays in the brains of study participants who suffered from severe limb weakness. In a recently published study, they found that "two neural population dynamics features previously reported for arm movements were also present during speaking: a component that was mostly invariant across initiating different words, followed by rotatory dynamics during speaking. This suggests that common neural dynamical motifs may underlie movement of arm and speech articulators." Read study

The scientists were able to design software that could differentiate among different syllables uttered by two of the implanted participants who retained the power of speech.

By analyzing neural activity across nearly 200 electrodes, the scientists found they could identify which of several syllables a participant was saying – with more than 80% accuracy in the case of one participant.

The implication here is that someday it may be possible to figure out what people who, for one or another reason, can't speak are trying to say – and get a device to say it for them.

"There aren't a lot of opportunities to make measurements from inside someone's brain while they talk," said postdoctoral research fellow, Sergey Stavisky. If these two people hadn't just happened to have multi-electrode arrays implanted in the part of the brain responsible for hand-movement control, that area's connection to speech might never have surfaced.

professor Jelena Vučković
December 2019

Congratulations to Professor Jelena Vučković! She has been awarded the Institution of Engineering and Technology (IET) A F Harvey Engineering Research Prize. She will develop an on-chip integrated pulsed laser, which will revolutionize photonic technology and the applications that require these lasers, such as medicine, optical communications, quantum computing and self-driving cars.

Currently Ti:sapph lasers are bulky, expensive, table-top lasers, which can be limiting to applications such as LIDAR and microscopy. Jelena and her team are aiming to create a miniature version, which would have a total volume smaller than a cubic centimeter. This would have a major impact on photonic technology and society, by decreasing the cost and footprint of such lasers.

The new miniature lasers could also be applied to and used in several applications, such as miniaturized and inexpensive sensors in self-driving cars, which would make such LIDAR systems accessible to everyone; to pump quantum light sources for secure quantum communications where eavesdropping can be detected; and as compact sources for brain microscopy and imaging.

Jelena said: "I am tremendously honored to receive the A F Harvey Prize from the IET, and to be selected among the shortlisted group of very distinguished scientists. This prize will be used to support my lab's work on implementation of miniaturized and inexpensive ultrafast lasers – the greatest challenge of integrated photonics, which could revolutionize many applications, from self-driving cars, to neuroscience and to quantum technologies."

Sir John O'Reilly, Chair of the IET's Selection Committee for the Prize, said: "Professor Jelena Vuckovic's pioneering work on inverse photonic design is transforming our approach to the design and realization of new high-performance integrated systems - with wide-ranging applications in communications, lidar, quantum systems and the like. She and her team at Stanford have developed inverse methods that cut the design time dramatically, thereby opening new vistas and radically different approaches to realization of elements not previously conceived. Finally, we see in prospect photonics realizing its untapped potential, helping us to 'engineer a better world'."

The IET's A F Harvey Research Prize, worth £350,000, is named after Dr A F Harvey who bequeathed a generous sum of money to the IET for a trust fund to be set up in his name for the furtherance of scientific research into the fields of Radar and Microwaves; Lasers and Optoelectronics; Medical Engineering.

Jelena will present a prize lecture on her research at IET London: Savoy Place on 16 March 2020.

 

Please join us in recognizing Jelena for her extraordinary research!

professor Jelena Vučković
December 2019

Professor Jelena Vučković and team recently published "4H-silicon-carbide-on-insulator for integrated quantum and nonlinear photonics" in Nature Photonics.

Photonic chips could become the basis for light-based quantum computers that could, in theory, break codes and solve certain types of problems beyond the capabilities of any electronic computer.

In recent months Jelena has created a prototype photonic chip made of diamond. Now, however, in experiments described in Nature Photonics, she and her team demonstrate how to make a light-based chip from a material nearly as hard as diamond but far less exotic — silicon carbide.

"These are early stage but promising results with a material that is already familiar to industry," Jelena said.

Commonly used in brake pad linings, silicon carbide is a tough material that has carved out a new niche in electronics, where it is used to make chips for high-voltage, high-heat applications, such as electric car power supplies, that are too extreme for ordinary silicon chips.

Like most chip-making materials, silicon carbide is a crystal — a group of specific atoms arranged in a consistent lattice. In a silicon carbide crystal, every silicon atom is joined to four carbon atoms to form a strong, three-dimensional lattice. The stability of this lattice helps makes silicon carbide useful for high-heat applications, whether that involves dealing with friction in brake pad linings or high currents flowing through chips.

Daniil Lukin (EE PhD candidate), Constantin Dory (EE PhD candidate) and Melissa Guidry (AP PhD candidate) led the effort to make this crystal useful as a photonic chip. They removed silicon atoms at strategic locations throughout the lattice. Each vacancy in the lattice created a subatomic trap that captured a single electron from one of the surrounding carbon atoms. To make the light-based chip work, the researchers sent a stream of photons through the lattice. Whenever a photon struck a trapped electron, the collision between those two particles sent a photon spinning off at a particular energy level, or what scientists call a quantum. Interactions between photons and electrons create what scientists call a qubit, or quantum bit. A qubit is roughly analogous to the transistor in an electronic chip — the fundamental unit that makes the system work.

Many hurdles must still be overcome before photonic chips made of silicon carbide, or diamond for that matter, might become useful as the building blocks for a quantum computing system. "Hype tends to get ahead of science," Vuckovic says. But within the next five years or so, she envisions using photonic chips to send data via quantum light through fiber optic cables, making such communications more secure by making it possible to detect efforts to tap into the flow of information.

As the director of Q-FARM — short for Quantum Fundamentals, Architecture and Machines — Jelena is helping to bring together researchers from Stanford and the SLAC National Accelerator Laboratory to solve the nitty-gritty hardware and software challenges necessary to make quantum technology a reality.

"We're trying to take small, practical steps," she says, "while we try to push beyond the limits of our current understanding and discover new platforms for quantum technologies."

professor Gordon Wetzstein
November 2019

Congratulations to Professor Gordon Wetzstein! He has been awarded the 2020 SPIE Early Career Achievement Award – Academic Focus – in recognition of outstanding contributions to computational imaging and display technologies. The SPIE Early Career Achievement Award recognizes significant and innovative technical contributions in the engineering or scientific fields of relevance to SPIE.

"Gordon's core research interests lie in computational imaging and photography, i.e. at the intersection of several disciplines including optics, image processing, computer vision, photography, and human perception," notes Professor Wolfgang Heidrich, the director of the King Abdullah University of Science and Technology's Visual Computing Center. "This is an emerging research area that promises to revolutionize both photography and display technologies, as well as other applications of optics through the introduction of computation, thereby enabling more robust, less expensive, and more portable optical devices. Even more importantly, it allows for completely new imaging modalities that have not been possible so far. Gordon has a clear and articulate vision of research in Computational Photography and Displays — in fact he is probably the first to really define Computational Displays as a separate sub-area with similar but distinct challenges from Computational Photography — and has been extremely active providing leadership to the community. He is an emerging star."

Please join us in congratulating Gordon for his tremendous contributions!

EE Professor Eric Pop's research was recently published in Science Advances.

Research in the Pop Lab has shown that a few layers of 2D materials can provide the same insulation as a sheet of glass 100 times thicker. "Thinner heat shields will enable engineers to make electronic devices even more compact than those we have today. We're looking at the heat in electronic devices in an entirely new way," reports Pop.

Detecting thermal vibrations
Thinking about heat as a form of sound inspired the Pop Lab researchers to borrow some principles from the physical world. "We adapted that idea by creating an insulator that used several layers of atomically thin materials instead of a thick mass of glass," said lead author Sam Vaziri, Electrical Engineering postdoc.

The team used up to four different compounds: graphene, molybdenum diselenide, molybdenum disulfide and tungsten diselenide – each three atoms thick – to create a four-layered insulator just 10 atoms deep. Despite its thinness, the insulator is effective because the atomic heat vibrations are dampened and lose much of their energy as they pass through each layer.

"As engineers, we know quite a lot about how to control electricity, and we're getting better with light, but we're just starting to understand how to manipulate the high-frequency sound that manifests itself as heat at the atomic scale," Pop said.
