Cascadable photonic circuits with nonlinear amplitude thresholders

A non-transitory computer-readable storage medium comprising stored instructions that, when executed by at least one processor, cause the at least one processor to:

• instruct one or more photonic input gates of a photonic circuit to receive one or more photonic input signals and generate one or more photonic signals based on the one or more photonic input signals;
• instruct a first set of one or more photonic gates of the photonic circuit coupled to the one or more photonic input gates to generate one or more intermediate photonic output signals based on the generated one or more photonic signals;
• instruct at least one nonlinear amplitude thresholder of the photonic circuit coupled to the first set of one or more photonic gates to generate at least one photonic thresholding signal based on at least one of the one or more intermediate photonic output signals, the at least one nonlinear amplitude thresholder operating in at least one of a first operating regime, a second operating regime, and a third operating regime;
• and
• instruct a second set of one or more photonic gates of the photonic circuit coupled to the at least one nonlinear amplitude thresholder to generate one or more photonic output signals based at least in part on the at least one photonic thresholding signal.

A method comprising:

• receiving, at one or more photonic input gates of a photonic circuit, one or more photonic input signals;
• generating, by the one or more photonic input gate, one or more photonic signals based on the one or more photonic input signals;
• generating, by a first set of one or more photonic gates of the photonic circuit coupled to the one or more photonic input gates, one or more intermediate photonic output signals based on the generated one or more photonic signals;
• generating, by at least one nonlinear amplitude thresholder of the photonic circuit coupled to the first set of one or more photonic gates, at least one photonic thresholding signal based on at least one of the one or more intermediate photonic output signals, the at least one nonlinear amplitude thresholder operating in at least one of a first operating regime, a second operating regime, and a third operating regime;
• and
• generating, by one or more second photonic gates of the photonic circuit coupled to the at least one nonlinear amplitude thresholder, one or more photonic output signals based at least in part on the at least one photonic thresholding signal.
