Abstract

The invention provides a device capable of generating three-dimensional plasma photonic crystals and provided with three discharge air gaps. The device comprises a vacuum reaction chamber, two water electrodes arranged in the vacuum reaction chamber and a plasma generation power supply electrically connected with the water electrodes, wherein two solid borders which are attached to each other are arranged between the two water electrodes, the thicknesses of the two solid borders are different, a plurality of rectangular through holes are formed in the two solid borders, the rectangular through holes in the two solid borders are perpendicular to each other, the rectangular through holes in the two solid borders are crisscrossed to form a net-shaped through hole structure, and the through holes and the position of the thickness of the single solid border between the adjacent through holes jointly form a discharge air gap. According to the invention, different types of three-dimensional plasma photonic crystals are formed in the three discharge air gaps which are arranged in a staggered manner for the first time.

Description

technical field [0001] The invention relates to the fields of plasma application and optical technology, in particular to a device capable of producing three-dimensional plasma photonic crystals with three discharge air gaps. Background technique [0002] Photonic crystals, also known as photonic bandgap materials, are an artificial "crystal" structure formed by arranging two dielectric materials with different dielectric constants in space at a certain period (the size is on the order of the wavelength of light). In recent years, plasmonic photonic crystals, as a new type of photonic crystals, have received extensive attention and research from scholars at home and abroad, and are expected to be used in many electromagnetic wave control fields such as filters, optical switches, plasmonic lenses, and plasmonic stealth. The dielectric constant of photonic crystals is a periodic function of space, and plasmonic photonic crystals are periodic structures formed by the interlacin...
