Abstract

The invention relates to nanometer photoelectron equipment, in particular to an adjustable near-infrared band plasma bi-induction transparent nanometer device. The device comprises a metallic silver interlayer, wherein a rectangular cavity and three cylindrical hole cavities, namely the first cylindrical hole cavity, the second cylindrical hole cavity and the third cylindrical hole cavity, with the same radius are embedded in the metallic silver interlayer; the rectangular cavity, the first cylindrical hole cavity, the second cylindrical hole cavity and the third cylindrical hole cavity are filled with the dielectric material polycrystal indium tin oxide; on the cross section, the first cylindrical hole cavity, the second cylindrical hole cavity and the third cylindrical hole cavity form an equilateral triangle topological structure, and the circle center distance between any two cylindrical hole cavities is smaller than double of the circle radius; the axial lead of each cylindrical hole cavity is perpendicular to the rectangular cavity. By the adoption of the device, near-infrared band plasma bi-induction transparency is realized, and blue shift and red shift of near-infrared wavelength can be controlled.

Description

Technical field [0001] The invention relates to a nano optoelectronic device, in particular to an adjustable near-infrared waveband plasma dual-induced transparent nano device. Background technique [0002] Due to the strong dispersion effect in the transparent window, similar to a classic electromagnetic field induced transparency, Plasmonic-induced transparency (PIT) has potential applications in integrated photonic devices, slow light, all-optical data processing, and nonlinear optical processing. Different plasma structures, such as metal-dielectric material-metal (MDM, metal photonic crystals, metal molecules, etc.) have been used to explore the PIT effect. In recent years, among these structures, people have paid much attention to MDM plasma waveguides. They are popularized and applied to PIT. This is because they are easy to fabricate and have sub-wavelength light limitation, and have a plasmon propagation length. In recent studies, according to the relevant interference p...
