How it’s going The pixel-sized spectrometer operates very quickly; the entire process happens in less than a millisecond. And it’s already proven to be as accurate as conventional spectrometers, with sensitivity that rivals commercial photodetection devices. “Moving to a single photodetector element allows for simple miniaturization that is very difficult to achieve using dispersive optics […]

In this episode of Photonics Hot List: NLM Photonics has sent its silicon organic hybrid electro-optic photonic chips to the International Space Station as part of a NASA mission meant to test the materials’ durability by exposing them to harsh conditions in space. SPIE has announced the finalists for the 2026 Startup Challenge. The ceremony

Aluvia Photonics Founded in 2022 as a spinoff from the University of Twente, Aluvia Photonics pioneers PICs based on aluminum oxide (Al2O3)—a material poised to fill one of the last major gaps within the photonics spectrum. Unlike indium phosphide, silicon, or silicon nitride (Si3N4) platforms, Al2O3 offers an exceptionally wide transparency window that extends from the

This episode features Dirk Hauschild, a senior strategic marketing expert with Focuslight Technologies. He talks with host Justine Murphy about his more than 30 years of experience in the design, development, and integration of micro-optical components and systems, his work with Focuslight, and his thoughts on the future. Following the Photons: A Photonics Podcast dives

In an advance for organic infrared photodiodes, researchers at the University of Turku in Finland recently engineered strong exciton-photon coupling to create a device with an exceptionally narrow detection band and high responsivity—without separate filters. The team’s organic infrared photodiode is ultrafast and its measured responsivity is competitive with leading organic approaches. “I’ve always been
