Abstract

The invention provides a terahertz wave modulator and a method, and belongs to the technical field of optics. The terahertz modulator comprises a nanostructure layer and a two-dimensional material layer, wherein the nanostructure layer is arranged on one side of the two-dimensional material layer; the nanostructure layer and the two-dimensional material layer are stacked to form a heterojunction; the nanostructure layer comprises a plurality of nanostructures which are periodically arranged; the two-dimensional material layer comprises at least one layer of two-dimensional material with nonlinear conductivity. According to the terahertz modulator provided by the embodiment of the invention, the high-order nonlinear effect of the incident terahertz wave is enhanced for multiple times, and the modulation depth of the terahertz wave is enhanced, so that the nonlinear modulation of the terahertz wave is realized.

Description

technical field [0001] The present application relates to the field of optical technology, in particular, to a terahertz wave modulator and method. Background technique [0002] Terahertz technology has been rated as "Top Ten Technologies Changing the Future World". Terahertz waves are between the microwave band and the infrared band, and combine multiple disciplines such as optoelectronics, semiconductors and materials. An area of ​​research that is being vigorously developed. [0003] Related technologies realize the modulation of terahertz waves by changing the gate voltage of semiconductor heterojunction field effect transistors to regulate the opening and closing of artificial unit openings of metamaterials. [0004] In the process of implementing the present application, the inventors found that there are at least the following problems in the related art: [0005] Terahertz wave modulators based on semiconductor (such as gallium nitride) materials in the prior art c...
