Moving beyond passive alignment MicroAlign developed a micromanipulation platform to actively align individual fibers with nanometer-level precision. Traditional fiber arrays rely on passive placement into precision V-grooves, where mechanical tolerances accumulate across channels. Active alignment, by contrast, dynamically adjusts fiber position during assembly, correcting pitch deviations before permanent fixation. This approach enables multichannel arrays optimized […]

Xiaoke Yi’s group at the University of Sydney in Australia designed and built an AI nanophotonic chip prototype that manipulates light to perform calculations at a picosecond timescale (trillionths of a second)—the time it takes light to travel through its nanostructures (each one is tens of micrometers). The group’s combined on-chip nanostructures form a neural

This episode features Vivek Raghunathan, cofounder and CEO of Xscape Photonics, a Columbia University spinoff focused on silicon photonics and artificial intelligence (AI). He has nearly two decades of experience in the silicon photonics sector, including at Intel.  In this chat, he talks with host Justine Murphy about Xscape Photonics and its innovative work, as

In this episode of Photonics Hot List: 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 up as environmental monitoring sensor networks, too. Business news roundup: Strategic partnerships are in the works between Oxide
