Embodiment 1

[0023] Example 1, a device for producing a solid-modulated plasmonic photonic crystal with three refractive indices.

[0024] Such as figure 1 As shown, the device used in the present invention is specifically: two airtight dielectric containers are symmetrically arranged in a horizontal cylindrical vacuum reaction chamber 1, and water is injected into the airtight dielectric container to form two opposite water electrodes. 2. The two water electrodes 2 are electrically connected with the plasma generating power source 5 outside the vacuum reaction chamber 1 . In this embodiment, the water electrode 2 is made of a plexiglass tube sealed by glass baffles 3 at both ends, the plexiglass tube is filled with water, and a copper ring 4 is set in the plexiglass tube. The two copper rings 4 are respectively electrically connected to the positive pole and the negative pole of the plasma generation power supply 5 through power lines. The thickness of the glass block 3 is between 1.5 ...

Abstract

The invention provides a method for generating solid modulation plasma photonic crystals with three refractive indexes. The method includes three steps that two water electrodes which are electrically connected with a plasma generation power supply are arranged in a vacuum reaction chamber; a solid frame is arranged between the two water electrodes, a plurality of through holes in matrix array are formed in the internal region of the solid frame, and every two adjacent through holes are partitioned through a solid ridge; air is fed into the vacuum reaction chamber as discharging gas, and pressure of the discharging gas is regulated to 0.1-0.4atm; a switch is turned off, and the solid modulation plasma photonic crystals with three refractive indexes, which are composed by periodic arraying of plasma, gas and the solid ridges, can be generated in discharging gaps. By the method, the solid modulation plasma photonic crystals with three refractive indexes are generated for the first time, transmission of light at certain frequencies can be blocked, frequency selective light switching effect is achieved, and the method has broad application prospect in the industrial field.

Description

technical field [0001] The invention relates to the field of plasma application technology and optical technology, in particular to a method for producing a solid-modulated plasma photonic crystal with three refractive indices. 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). The dielectric constant of a photonic crystal is a periodic function of space. If the periodic modulation of photons by the dielectric coefficient is strong enough, the photon energy propagating in the photonic crystal will also have an energy band structure, and photon "forbidden" will appear between the bands. band", photons whose frequency falls in the forbidden band cannot propagate in the crystal. The position and shape of the photonic forbidden band depend...
