Quantum advance High-dimensional quantum technologies “require simultaneous, real-time access to many optical modes—particularly for applications involving feedback and control,” says Kalash. “In quantum computing, for example, multimode squeezed states can be combined to form complex entangled cluster states in which the modes act as interconnected nodes of a computational network. The ability to monitor many […]

In contrast, the Tm:YLF curve scales rapidly as the pump duration is extended and reaches a clear operational threshold, where it achieves a true transparency state at a 2-ms pump duration. From this point, the output scales aggressively and climbs into the multi-joule regime and peaks around an optimized 20-ms pump window to deliver an

Light News: Quantum Edition features a quick roundup of some of the coolest, most exciting news impacting the quantum sector of the photonics industry. Following the Photons: A Photonics Podcast dives deep into the fascinating world of photonics and optics. Join us as we bring you the latest news and insights from the forefront of

The semiconductor industry is undergoing one of its most significant transitions since the advent of extreme ultraviolet (EUV) lithography. While transistor scaling continues to drive improvements at the device level, system-level performance is increasingly achieved through advanced packaging technologies. Architectures based on chiplets, high-bandwidth memory (HBM), and three-dimensional (3D) heterogeneous integration enable higher bandwidth, lower

Artificial intelligence (AI) is moving out of the cloud and into physical environments, and machines are now being asked to do much more than simply process data. They must perceive, understand, and interact with the real world in real time. Whether navigating a warehouse, monitoring occupancy inside a smart building, assisting healthcare professionals, or enabling

Astha Chaturvedi, a postdoctoral researcher at the University of Surrey, and colleagues recently put an ultrablack coating developed by spinout Surrey NanoSystems to the test by measuring  how it reflects light under a range of illumination and viewing conditions, and then simulated how a coated satellite within low Earth orbit (LEO) would appear to observatories

Electrical current shows sensitive response to relative optical phase One of the coolest aspects of this work for Gong was discovering just how sensitively the electrical current responds to the relative optical phase. Because the current is controlled by the relative phase between the two absorption pathways, a change in optical path length of only

By the time an optic failure appears in a high-power laser system, the root cause may have started much earlier—it’s not always a coating defect. Often, the issue begins with a mismatch between what the specification says and what the laser system needs. A mirror, window, or beamsplitter may meet the requested values for reflectivity,

In this episode of Photonics Hot List: Scientists at the NSF-DOE Vera C. Rubin Observatory in Chile have embarked on a 10-year mission that will ultimately create a time-lapse record of our Universe. Business news roundup: Pilot Photonics is set to receive funding they say will help boost the company’s international presence. Ouster reports strong

Laser radar systems are often judged by familiar top-level metrics such as range, spot size, or scan speed. For vibration and precision measurement work, however, the underlying question is different: How much useful dynamic information can the system capture from the scene during the same physical event? This question matters in structural testing, industrial diagnostics,
