A group of researchers led by Meng Han, an assistant professor of physics at Kansas State University, recently generated and characterized 18-attosecond isolated light pulses—and these are believed to be the shortest light pulses experimentally measured so far. Ever-shorter and brighter light pulses are a holy grail for ultrafast science, because these pulses offer a […]

In this episode of Photonics Hot List: A new holographic printer that uses a nanoscale nanopatterned mask is poised to revolutionize 3D printing. In the deep-tech sector, Mixx Technologies has acquired Sophic Silicon Technologies, while Solinide Photonics has received a new round of seed funding. Photonic time crystals are being hailed a potential gamechanger for

A new type of optical fiber created by Birgit Stiller’s Quantum Acoustics group at Max Planck Institute for the Science of Light (MPL) takes the core from liquid to frozen solid—and it continues to guide light and hypersonic sound waves, but with an impressively high in-fiber Brillouin gain (or optoacoustic coupling) of 434 W-1 m-1.

Still waiting for optical fiber at your home? For private households, this is an inconvenience. For critical infrastructure and cybersecure networks, it’s a make-or-break resource. Free-space optical QKD enables connectivity at sites and between platforms where fiber deployment is impractical or impossible—like connectivity with mobile users of critical infrastructures, across campuses, harbors, industrial areas, and

For decades, scanning microscopy has treated motion blur as a defect to be prevented. The familiar stop-and-stare workflow reflects this assumption: Move the specimen, halt the stage, wait for it to settle, expose the camera, and repeat. While it’s a reliable way to protect image quality, the repeated acceleration, settling, and exposure steps also make

In this episode of Photonics Hot List: A new light perception-based underwater digital twin robotic hand system could help identify natural resources that are currently untapped in Earth’s oceans. Business news roundup: Quantum cascade laser-based product manufacturer Block Engineering has named a new chief operating officer. And ZuriQ, a Swiss quantum computing spinout, has secured

When we think about a technology we can’t live without, the mobile phone is often near the top of the list. It has become far more than a telephone and influences how we work, communicate, conduct research, navigate, consume media, read, shop, and organize our lives. This outcome was far from obvious during the early

In this episode of Photonics Hot List: A perception-driven approach to display design could lead to more practical, photorealistic augmented-reality (AR) glasses. French research institute CEA has entered a strategic collaboration with deep-tech venture capital firm Playground Global to ultimately boost commercialization of deep technologies. Show off your photonics, optics, and quantum innovations via the Laser

Processing the data onsite To process the data onsite, we got a Lenovo Legion 9 with an RTX 5080 up and running from the first session to drive the scanners and give us a way to view the images and data we’d captured. A lagging machine would have cost us time when we needed to

A few years ago, while using NASA’s James Webb Space Telescope (JWST) to survey some of the Universe’s earliest galaxies, astronomers noticed a peculiar and extremely bright “Little Red Dot” they’ve since concluded is a mashup of a black hole and a star. This massive Black Hole Star cranks out 100 billion times more energy
