Abstract

The invention discloses an optical clock generator. The optical clock generator comprises a nonlinear cavity unit, a cross-shaped waveguide logic gate unit and a time delayer unit. The optical clock generator is of a six-port photonic crystal structure and is composed of two reference light signal input ends, a feedback signal input end, a system signal and feedback signal output end and two idle ports. The output end of the cross-shaped waveguide logic gate unit is connected with the input end of the nonlinear cavity unit, the system signal output end of the nonlinear cavity unit is connected with the input end of the time delayer unit, the output end of the time delayer unit is connected with the input end of the cross-shaped waveguide logic gate unit, a signal output end is connected with a two-branch waveguide, one end of the two-branch waveguide serves as a system output port, the other end of the two-branch waveguide serves as a feedback signal output port connected to the input end of the time delayer unit, and the time delayer unit performs time delay on an input signal which is output to a feedback signal input end. The optical clock generator and other optical logic elements are easy to integrate.

Description

technical field [0001] The invention relates to a two-dimensional photonic crystal, nonlinear optics, and an optical clock generator. Background technique [0002] In 1987, E. Yablonovitch of Bell Laboratories in the United States was discussing how to suppress spontaneous emission, and S. John of Princeton University was discussing the photonic region and independently proposed the concept of photonic crystal (Photonic Crystal). A photonic crystal is a material structure in which dielectric materials are periodically arranged in space, and is usually an artificial crystal composed of two or more materials with different dielectric constants. [0003] With the introduction and in-depth research of photonic crystals, people can more flexibly and effectively control the movement of photons in photonic crystal materials. In combination with traditional semiconductor technology and integrated circuit technology, people are making rapid progress towards all-optical processing th...
