Researchers at Lawrence Livermore National Laboratory and Stanford University say they have built a two-photon lithography system that could push 3D nanofabrication toward manufacturing scale, boosting throughput by more than 1,000 times compared with commercial tools while maintaining minimum feature sizes of 113 nanometers. Two-photon lithography uses ultrafast laser pulses to harden material only at…
World’s largest 3,200-megapixel camera begins capturing 20 billion galaxies at NSF-DOE Rubin Observatory
The NSF-DOE Vera C. Rubin Observatory unveiled its first images today, showcasing a 3,200-megapixel digital camera that promises to capture more data about our universe than all optical telescopes throughout history combined, according to Brian Stone, performing the duties of the NSF director. In 10 hours of test observations from its mountaintop perch in Chile,…
Sandia Truman Fellows advance quantum optics from lab to wafer-scale and field applications
Two Harry S. Truman Fellows are undertaking research to translate advanced quantum optical principles from laboratory concepts into scalable, manufacturable devices. Truman Fellow Sam Peana focuses on quantum photonics research. As a doctoral student, he contributed to a team thaat identified a novel single-photon emitter found in silicon nitride-oxide materials. He subsequently developed techniques for…
R&D 100 winner of the day: Berxel iHawk P100 Polarization Structured Light Camera
Berxel Photonics Co. Ltd.’s new 3D camera using Polarization-Structured Light (PSL) transforms depth perception in challenging environments. Traditional 3D cameras struggle with reflective surfaces like glass, mirrors, and water, often producing inaccurate depth readings. The PSL 3D camera overcomes these limitations by leveraging the polarization properties of light. It employs high-contrast-grating vertical-cavity surface-emitting lasers (VCSELs)…
