Photonic crystal all-optical OR conversion logic gate

Abstract

The invention discloses a photonic crystal all-optical OR conversion logic gate which comprises a photonic crystal structural unit, an optical switch unit, a reference light source, a wave-absorbing load and a D trigger unit, wherein two system signal input ends of the optical switch unit are connected with a logic signal X1 and a logic signal X2; the reference light source is connected with a reference light input end of the optical switch unit; three middle signal output ends of the optical switch unit are respectively connected with two middle signal input ends of the photonic crystal structural unit and the wave-absorbing load; a clock control signal CP is connected with a clock signal CP input end of the optical switch unit and a clock signal input end of the D trigger unit through the input ends of a two-branch waveguide; the output end of the photonic crystal structural unit is connected with a D signal input end of the D trigger unit. The photonic crystal all-optical OR conversion logic gate has the advantages of compact structure, high operating rate, high anti-jamming capability and easiness in integration with other optical logic elements.

Description

technical field [0001] The invention relates to two-dimensional photonic crystals, optical or logic gates 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 through the design and manufac...
