Abstract

The invention discloses a device and method for generating nested plasma photonic crystals with multiple structures. The device comprises a vacuum reaction chamber and two water electrodes arranged in the vacuum reaction chamber, wherein a glass hexagon electric discharge boundary with a 2.4-mm thickness is arranged between the two water electrodes, an air inlet is arranged on a wall body of the vacuum reaction chamber, and a hollow spiral tube heating coil is arranged in the vacuum reaction chamber. The method for generating the nested plasma photonic crystals comprises the following steps that: the two water electrodes can be heated to be 348K-358K; and the nested plasma photonic crystals with multiple structures can be generated by controlling the discharge conditions, i.e. the voltageamplitude is controlled to be 4.3kV-5.2kV, the frequency is controlled to be 53kHz, the air pressure p is controlled to be equal to 0.5Pa, and the argon content in mixed gas is controlled to be 75%-90%. The plasma photonic crystals disclosed by the invention have the advantages of preventing lights with different frequencies from spreading, playing roles of optical modulators and having wide application prospects in industrial fields.

Description

technical field [0001] The invention relates to the field of plasma application technology and the field of optics, in particular to a device and method for producing plasma photonic crystals with various nested structures. Background technique [0002] Plasma photonic crystals are a new type of photonic crystals in which plasma and other media are periodically arranged. Compared with traditional photonic crystals, the biggest feature of plasmonic photonic crystals is that their structures can be adjusted in time and space, so that their corresponding photonic band gaps can be adjusted. By adjusting the lattice constant, dielectric constant, lattice symmetry, and time period of the plasmonic photonic crystal, people can change its energy band position and width, so that the light whose frequency falls into the band gap is prohibited from propagating, and realizes the control of light. Frequency selection and control of light propagation. Based on the above characteristics,...
