Xscape is building multicolor lasers to connect chips within datacenters

Xscape, a startup founded by Columbia professors, is developing lasers to drive the fiber-optic interconnects in datacenters.

Xscape is based in Santa Clara in the heart of Silicon Valley, but has its roots in a Columbia University lab, where three professors — Alexander Gaeta, Keren Bergman, and Michal Lipson — invented a technique they believed could be used to transmit terabytes of data over light. Xscape says that it’s “actively engaged” with ten customers for potential deployments, ranging from vendors to hyperscalers — and that it has secured funding from Cisco and Nvidia, whose venture arms invested in its recent $44 million Series A round. “The funding will allow Xscape to push the boundaries of our platform and integrate it with simulation, high-performance compute, and AI software to help customers in all industries take their innovations to new heights,” Raghunathan said.
