LFW: What advantages does optical compute offer that currently available compute infrastructure doesn’t? Steinman: Optical compute is well suited to accelerate mathematical operations central to AI and scientific workloads, particularly linear operations such as vector-matrix multiplication. Our PACE 2 platform, for example, uses a 128 × 128 configurable optical matrix multiplier and a heterogeneous optoelectronic […]

CN center: A more robust silicon defect Our team identified a promising alternative to the T center: the CN center, which consists of carbon (C) and nitrogen (N) atoms (see Fig. 2, right). The CN center is chemically similar to the T center because N has the same number of protons and electrons as C+H.

This edition features Yvain Thonnart, a chief scientist in the digital integrated circuits and systems division of the French research institute CEA-List, where he focuses on areas including networks-on-chip and integrating emerging photonics technologies. He talked recently with host Justine Murphy about his work at CEA, and his team’s potentially gamechanging development of the first

Our methodology has also been used operationally for several years by astronomers to support telescope alignment and optical performance evaluation under real observing conditions—which demonstrates the approach is effective not only within laboratory environments, but also for practical field applications under atmospheric seeing conditions (stability of the Earth’s atmosphere). Beyond accuracy, the computational architecture also

One key part of the race to put clean laser-driven fusion energy on the grid by the 2030s or 2040s involves gaining a better understanding of the complex behavior of the plasma (a superhot ionized gas) generated. A new study led by researchers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) helps

In this episode of Photonics Hot List: Projection mapping is often used for entertainment purposes. But a new approach overcoming a key longstanding challenge could expand use of this lighting technique. In the finance realm, eyeo can now more easily advance its design capabilities, while OpenLight Photonics is working to accelerate its overall strategic roadmap.

An optical computer prototype developed by Xingjie Ni, an associate professor of electrical engineering at Penn State School of Electrical Engineering and Computer Science, and his team opens up a more realistic path to reduce the energy demands of artificial intelligence (AI) computation. Their work was inspired by the growing mismatch between the computational demands

In this episode of Photonics Hot List: Drawing inspiration from a mantis shrimp’s vision, researchers at the University of Illinois at Urbana-Champaign have developed a compact, single-chip multiwavelength camera. Business new roundup: EPIC has announced the recipient of its 2026 CEO Award, while a British developer of infrared technologies like quantum dots and imagers has received

The work is part of the European Union-funded intent and context-aware optical networks (ICON) project. “ICON is a unique approach to the integrated communication and sensing paradigm,” says Aleksandra Kaszubowska, an assistant professor of electronic and electrical engineering at Trinity, as well as an assistant professor and research fellow at CONNECT. “Our aim is to

During the early 2010s, regulatory agencies increased scrutiny of implantable medical devices. In response, in 2012 we created Sensofar Medical as a new division within the Sensofar Group. Its purpose was to apply Sensofar’s optical surface measurement and inspection technology to biomedical and medical device manufacturing, with a particular focus on implantable devices such as
