Photonic interposers that enable low-power, high-bandwidth inter-chip (e.g., board-level and/or rack-level) as well as intra-chip communication are described. Described herein are techniques, architectures and processes that improve upon the performance of conventional computers. Some embodiments provide photonic interposers that use photonic tiles, where each tile includes programmable photonic circuits that can be programmed based on the needs of a particular computer architecture. Some tiles are instantiations of a common template tile that are stitched together in a 1D or a 2D arrangement. Some embodiments described herein provide a programmable physical network designed to connect pairs of tiles together with photonic links.

Photonic communication platform and related circuits

Described herein are photonic sources and related system architectures that can satisfy the optical power requirements of large photonic accelerators. Some embodiments relate to a computer comprising a photonic accelerator configured to perform matrix multiplication; a fiber array optically coupled to the photonic accelerator; and a photonic source optically coupled to the fiber array. The photonic source comprising a laser array comprising a plurality of monolithically co-integrated lasers, and a coupling lens array comprising a plurality of monolithically co-integrated lenses, the coupling lens array optically coupling the laser array to the fiber array. The laser array is configured to output between 0.1 W and 10 W of optical power.
