Abstract
A reservoir computing system comprises an input system configured to generate an input signal, an optical reservoir configured to receive the input signal from the input system, and an output system configured to generate an output signal based on light received from the optical reservoir. The optical reservoir comprises a plurality of reservoir lasers configured for injection-locked operation and a reservoir randomization element configured to randomly distribute light output by the plurality of reservoir lasers among the plurality of reservoir lasers to contribute to injection locking of the plurality of reservoir lasers.
Claims20
A reservoir computing system, comprising:
- an input system configured to generate an input signal;
- an optical reservoir configured to receive the input signal from the input system, the optical reservoir comprising:
- a plurality of reservoir lasers, wherein each reservoir laser of the plurality of reservoir lasers is configured for injection-locked operation;
- and
- a reservoir randomization element configured to randomly distribute light output by the plurality of reservoir lasers among the plurality of reservoir lasers to contribute to injection locking of the plurality of reservoir lasers;
- and
- an output system configured to generate an output signal based on light received from the optical reservoir.
An optical reservoir for a reservoir computing system, the optical reservoir comprising:
- a reservoir laser array comprising a plurality of reservoir lasers arranged in an array, wherein each reservoir laser of the reservoir laser array is configured for injection-locked operation;
- a randomly diffuse screen arranged to receive light output by the reservoir laser array, wherein the randomly diffuse screen is configured to (i) diffusely reflect incoming light toward the reservoir laser array to contribute to injection locking of the plurality of reservoir lasers and (ii) diffusely transmit incoming light toward an output system;
- and
- a reservoir lens intervening between the reservoir laser array and the randomly diffuse screen.
