This episode of Following the Photons is a technical conversation about co-packaged optics, the rapid rise of interest in this technology, and why active alignment is a major manufacturing bottleneck in photonics. The discussion, sponsored by Aerotech, focuses on the company’s new PICAlignTM approach, developed in collaboration with SENKO and Santec, which aims to improve […]

This episode features Dr. Aleksandra Kaszubowska, an assistant professor of electronic and electrical engineering at Trinity College Dublin and an assistant professor and research fellow at the CONNECT Research Center. She talked with host Justine Murphy about the exciting work her team is doing, as well as her vast research experience and the remarkable path

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

In this edition of Following the Photons’ Light News: Researchers in Hong Kong developed a metasurface-based optical learning machine that boosts optical neural network scalability.   Existing fiber-optic cables underground and under the sea in much of Europe could soon become more than just lines of communication. Thanks to a new initiative, they could someday double

In an intriguing advance for metasurfaces, researchers at Monash University’s School of Physics and Astronomy in Australia came up with a disordered mosaic design approach—nanostructured materials that perform multiple simultaneous optical functions within a single device. The idea of a mosaic-style design for metasurfaces came to Haoran Ren, an Australian Research Council Discovery Early Career
