Optical circuit and method thereof

An optical logic circuit comprising:

• an optical input path configured to provide an optical logic input;
• a first optical coupler configured to combine the optical logic input with a first optical reference signal and generate an optical input signal;
• an optical resonator configured to receive the optical input signal, and further configured to:
• provide a first optical output signal in response to the optical input signal exceeding an intensity threshold, or
• provide a second optical output signal in response to the optical input signal being below the intensity threshold;
• and
• a second optical coupler configured to combine one of (i) the first optical output signal and (ii) the second optical output signal with a second reference signal to generate an optical logic output corresponding to (i) a first logic state associated with the first optical output signal or (ii) a second logic state associated with the second optical output signal,
• wherein each of the first optical reference signal and the second optical reference signal allows for interferometric gain.

A method comprising:

• providing an optical logic input generated based on a plurality of logic inputs;
• combining the optical logic input with a first reference signal to generate an optical input signal;
• receiving, by a resonator including a nonlinear optical material, the optical input signal;
• providing, by the resonator, an optical output signal based on the optical input signal and an intensity threshold of the nonlinear optical material;
• and
• combining the optical output signal with a second reference signal to generate an optical logic output corresponding to an output logic state.
