This is the first of a multipart series featuring Robin Hawk, a pioneer in the optics and photonics industry who has codeveloped several technologies, including HDTV. She is now CEO of Galxyz LLC, a company she founded with her husband, Dan Hawk, where they’re developing next-generation technologies like nuclear diamond-powered ultraviolet quantum photonics platforms, end-to-end […]

After years of anticipation, AR glasses are finally reaching a pivotal point. As hardware design evolves to deliver lighter, slimmer, and more comfortable devices, we are on the cusp of making AR truly wearable for everyday life. This breakthrough is driven by the convergence of miniaturized components and scalable manufacturing that enable brands to develop

Galvanometer scanner and optical errors. The galvanometer scanner, while incredibly fast and agile, brings its own set of errors. F-theta lenses, which are used to translate the scanner’s angular motion into a flat focal plane, are not perfect and introduce spatial nonlinearities known as pincushion or barrel distortion (see Fig. 3). Furthermore, the laser beam

New solutions for process monitoring As the demand for precision and efficiency in laser processing grows, manufacturers struggle to maintain quality assurance with outdated methods. Manual inspections and conventional monitoring systems often lead to high error rates, increased scrap, production downtimes, and inefficient workflows. Common production challenges include unstable processes, high scrap rates, undetected process

Prototype quantum networks, pluggable fiber-optic quantum comms modules ahead Photon pairs produced by the group’s devices are ready to build prototype quantum networks for distributing quantum information. “We use a 1550-nm wavelength compatible with existing long-haul fiber infrastructure, and Professor Kumar’s group at Northwestern recently showed that quantum and classical signals can coexist on the

This episode features Brad Booth, CEO of NLM Photonics. He came to NLM with years of experience working on Meta platforms and Microsoft Azure, and has held roles at Dell, Intel, and Bell-Northern Research. Following the Photons: A Photonics Podcast dives deep into the fascinating world of photonics and optics. Join us as we bring

On one hand, “diamond stands out with the highest thermal conductivity among known crystals, which not only promises a significant power improvement through efficient heat management but also minimizes thermal distortions at high power levels,” says Zhenxu Bai, a professor of optics, vice dean of the School of Electronics and Information Engineering, and deputy director

A quantum “tornado” is a simplified term for an orbital vortex line, and work led by Maximilian Ünzelmann, a Complexity and Topology in Quantum Matter (ct.qmat) postdoctoral researcher at the Universities of Würzburg and Dresden in Germany, experimentally demonstrated electrons form these vortices within the momentum space of quantum semimetal tantalum arsenide (TaAs). Momentum space

Since Robert Hooke and Jan van Leeuwenhoek made their first studies of microorganisms with early microscopes, optical imaging has been at the forefront of advancing knowledge of life and organic materials. A key challenge within the life sciences is imaging photosensitive samples that can easily experience photobleaching, where the strength of the signal dims due
