Astronomers discover an extremely bright 'Little Red Dot' within the earliest galaxies of the Universe-dating back a few hundred million years after the Big Bang-and it appears to be a new type of astrophysical object.

The mission: A nine-hour access window to create a high-res digital twin of the Liberty Bell forced our team to combine four forms of optical capture and check every dataset before leaving Philadelphia.

In this episode: A perception-based AR display design approach, a strategic collaboration could boost deep-tech commercialization, 2027 Innovators Awards call for entries, and a new approach to scaling quantum technologies.

In a breakthrough, researchers in France and Germany demonstrate a photonic time crystal-with optical properties that change over time-and it has the potential to dramatically increase signal processing/optical computing rates.

This episode of Following the Photons: A Photonics Podcast examines the increasing number of optics and photonics technician training programs around the U.S.

Laser subsystems are a constraint in scaling quantum technologies, but advances in visible distributed feedback (DFB) lasers provide an alternative that offers intrinsic single-frequency operation, mode-hop-free tuning, and wafer-scale manufacturability.

Nvidia works with companies building quantum computers, including ones with photonics-based quantum processing unit (QPU) approaches, and provides a quantum platform they can integrate into and use to target performance improvements.

In this episode: Researchers design scalable solar panels for recycling plastics, this week's photonics business news, and an ultrablack coating combats light pollution.

Vexlum's CEO and Cofounder Jussi-Pekka Penttinen shares how the Finnish company differentiates itself, why they're expanding operations into the U.K., and three intriguing trends he sees emerging within the quantum space right now.

This episode of Following the Photons: A Photonics Podcast features Jerome Paye, CEO of laser-powered particle accelerator developer TAU Systems.
