Introducing Passage!Passage is a wafer-scale, programmable photonic interconnect that enables arrays of heterogeneous chips to communicate with unprecedented bandwidth and energy efficiency.Many types of chips can be integrated on top of Passage including CPUs, memory, and special-purpose accelerators.Transistors and photonics integrated side-by-side provide a simple, yet powerful interface that facilitates dynamic reconfiguration of the communications topology. 40 passage lanes fit in the space of a single optical fiber—enabling high speed, energy efficient communication between nodes while reducing packaging complexity and cost.
