Abstract
An optical clock generator includes a nonlinear cavity unit, a cross-waveguide logic gate unit and a delayer unit; and is of a six-port photonic crystal structure including 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 the cross-waveguide logic gate unit is connected with the input port of the nonlinear cavity unit whose system-signal output port is connected with the input port of said delayer unit whose output port 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 of which is used as the system-signal output port, and another is used as the feedback-signal output port and connected to an input port of said delayer unit, the delayer unit performs time delay on an input signal and outputs the signal to the feedback-signal-input port.
