Abstract
In example implementations, an optical gate is provided. The optical gate receives at least one optical signal via a waveguide of an optical memory gate. The optical gate compares a wavelength of the at least one optical signal to a resonant wavelength associated with a resonator. When the wavelength of the at least one optical signal matches the resonant wavelength, a value that is stored in the resonator is read out via the at least one optical signal. Then, the at least one optical signal with the value that is read out is transmitted out of the optical gate.

A method, comprising:
- receiving at least one optical signal via a waveguide of an optical memory gate;
- comparing a wavelength of the at least one optical signal to a resonant wavelength associated with a resonator;
- reading out a value that is stored in the resonator via the at least one optical signal when the wavelength of the at least one optical signal matches the resonant wavelength;
- transmitting the at least one optical signal with the value that is read out;
- monitoring a total power level of the optical memory gate, using a feedback loop;
- and
- resetting the value that is stored in the resonator when the total power level exceeds a power reset threshold value.
An optical memory gate comprising:
- a waveguide along which an optical signal and a pump power optical signal propagate;
- a first resonator in communication with the waveguide, wherein the first resonator stores a value and the optical signal reads out the value stored in the first resonator when a wavelength of the optical signal matches a resonant wavelength associated with the first resonator;
- a second resonator in communication with the waveguide, wherein the second resonator applies a phase shift to the pump power optical signal;
- and
- a feedback loop that monitors a total power level of the optical memory gate, wherein the value stored in the first resonator is reset when the total power level of the optical memory gate exceeds a power reset threshold value.
A method comprising:
- receiving a plurality of optical signals via a waveguide of an optical memory gate;
- comparing a wavelength of each one of the plurality of optical signals to a resonant wavelength associated with a resonator;
- reading out a value that is stored in the resonator via at least one optical signal of the plurality of optical signals when the wavelength of the at least one optical signal matches the resonant wavelength;
- transmitting the plurality of the optical signals including the at least one optical signal with the value that is read out;
- monitoring a total power level of the optical memory gate;
- and
- resetting the value that is stored in the resonator when the total power level exceeds a power reset threshold value.
