Building a laser stabilization system used to mean securing a bulky, expensive analog lock-in amplifier. While effective, these systems can be limited in flexibility, latency, and integration compared to modern digital approaches. Digital devices leveraging digital signal processing outperform their predecessors, which real-world case studies have shown. Is laser stabilization’s future digital? Laser stabilization is

Laser wavelengths required for many of today’s most intriguing experiments, particularly within the visible range, are a challenge to source for tiny photonic integrated circuits (PICs). But U.S. National Institute of Standards and Technology (NIST) photonics researchers and colleagues at Octave Photonics are spearheading a solution to this wavelength access issue—and also addressing challenges to

This edition features Host Justine Murphy’s chat with Dr. Brian Monacelli, a professor and director of Laser Technology at Pasadena City College in California. He’s also a principal optical engineer and supervisor of the Optical Implementation group at NASA’s Jet Propulsion Laboratory. They recently discussed things like the importance of training technicians in hands-on laboratory

In this episode of Photonics Hot List: A new terahertz imaging system developed by researchers in the U.K. is poised to become a key tool in medical diagnostics. Business news roundup: Photonics-centered startups continue to boom worldwide, with announcements of new rounds of funding. A new approach to coupling optical fibers to photonic integrated circuits

The digital world is accelerating at a pace that seemed implausible just a few years ago. Artificial intelligence (AI) models are doubling in size, which is causing data center traffic to explode and the infrastructure that powers our connected lives to strain under this unprecedented demand. Behind every AI breakthrough, real‑time analytics engine, and cloud‑scale

A retina-inspired biohybrid image sensor array (BIOPIX) created by a team of researchers led by Thomas M. Brown, a professor of organic and biological electronic engineering at Tor Vergata University of Rome in Italy, responds to light in a way remarkably similar to the photoreceptor cells of a retina—in terms of speed and how it
