Abstract
Embodiments of the present disclosure are directed to an integrated circuit with a photonic processor and an electrical analog memory. The integrated circuit further includes an array of photonic intensity modulators coupled to the photonic processor via a first set of optical connections, and an array of photodetectors coupled to the photonic processor via a second set of optical connections. The electrical analog memory is directly coupled to the array of photodetectors and the array of photonic intensity modulators.
Claims15
An integrated circuit, comprising:
- a photonic processor;
- an array of photonic intensity modulators coupled to the photonic processor via a first set of optical connections;
