Optical clock generator

An optical clock generator, wherein said optical clock generator, comprising a nonlinear cavity unit, a cross-waveguide logic gate unit and a delayer unit;

• said optical clock generator is of a six-port optical crystal structure, and including of two reference-light-signal input ports, a feedback-signal input port, a system signal and feedback-signal output port and two idle ports;
• the output port of said cross-waveguide logic gate unit is connected with the input port of said nonlinear cavity unit, and the system-signal output port of said nonlinear cavity unit is connected with the input port of said delayer unit;
• and the output port of the delayer unit is connected with the input port of the cross-waveguide logic gate unit, the system-signal output port is connected with a two-branch waveguide, one port of the two-branch waveguide is used as said system-signal output port, and another port is used as said feedback-signal output port and connected to an input port of said delayer unit, said delayer unit performs time delay on an input signal and outputs the signal to the feedback-signal input port.
