AI overview

optics.org reports that UK-based silicon photonics company Salience Labs has closed a $125 million Series B round, with the funds to be used to scale development of optical circuit switch (OCS) technology and ease network bottlenecks in AI data centers. Photonics.com reported the same day that the round was oversubscribed and noted that the company had previously demonstrated a 64-port all-optical silicon photonic circuit switch live at ECOC 2026. Electro Optics subsequently reported that the University of Oxford spin-out raised £95 million to scale optical circuit switch production and expand its presence in Silicon Valley. The reports give the funding amount in US dollars ($125 million) and pounds sterling (£95 million), respectively.
