Abstract

The invention relates to the technical field of optical fiber communication, and especially relates to an all-optical wavelength converter. The all-optical wavelength converter comprises a dielectric layer and an antenna layer which is formed on the surface of the dielectric layer and includes multiple periodically-arranged antenna structure units. Each antenna structure layer includes a first gap ring antenna, a second gap ring antenna and a square antenna with a square section, and the first gap ring antenna and the second gap ring antenna are symmetrically arranged on the two sides of the square antenna, wherein the first gap ring antenna and the second gap ring antenna are symmetric with any diagonal of the section as the axis of symmetry, and the gap of the first gap ring antenna and the gap of the second gap ring antenna face each other. The all-optical wavelength converter can achieve an all-optical wavelength conversion function, and is of simple structure and low cost. The application range of metamaterials is widened.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an all-optical wavelength converter. Background technique [0002] Metamaterial (Metamaterial) is an artificial extraordinary electromagnetic medium, which has extraordinary electromagnetic properties that natural materials do not have. Metamaterials generally use multiple artificially designed metal structural units to obtain negative permittivity, negative magnetic permeability, and negative refractive index, and the size of these metal structural units is much smaller than the wavelength of electromagnetic waves. The performance of metamaterials is not only related to the performance of the constituent materials, but also closely related to the size of the metal structural unit and the interaction between the units. Therefore, these metal structural units are also called superatoms or supramolecules. The most common metamaterials use metals to construct su...
