Lightmatter this week unveiled a pair of silicon photonic interconnects designed to satiate the growing demand for chip-to-chip bandwidth associated with ever-denser AI deployments.
The first of these is an optical interposer called the Passage M1000, which the California biz expects to begin shipping later this summer, and targets XPUs — think GPU or AI accelerators — or extremely high-bandwidth multi-die-switches on the order of petabits per second of capacity. The tech, which pipes data directly in and out of chips using light, was talked up by Lightmatter at the Optical Fiber Conference, running this week in San Francisco.
