Abstract

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.
