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

As electronic devices shrink and computing power demands soar, chip designs must become even more compact. This requires lasers with tighter beam stability, higher pulse‑to‑pulse energy consistency, and nanometer‑scale positioning accuracy. Bloom Laser, based in Pessac, France, designs and produces pulsed lasers of exceptional beam quality—with laser beam quality factor (M2) values <1.2. To achieve

In this episode of Photonics Hot List: A new laser platform by a team at Chalmers University of Technology in Sweden, which integrates optical components and hundreds of microscopic lasers on a one-centimeter chip, is paving the way for tiny biosensors that could potentially move lab testing from hospitals to homes.
