Problems solved by technology

At present, once the conventional photonic crystal is fabricated, its photonic band gap position is determined, and the optical band that can be selected has been determined. If you want to change the band gap position, you need to re-make the crystal, and it is difficult to realize the adjustability of electromagnetic waves. control

Abstract

The invention discloses a method and a special device for generating a time oscillation plasma photonic crystal. The method comprises the following steps of: 1, placing a discharge device in a vacuum tank, mixing a mixed gas of argon and air, and steam, and introducing the mixed gas and the steam in the vacuum tank and a discharge gap of the discharge device; and 2, changing a discharge conditionof the discharge device so as to change the static structure of the plasma photonic crystal into a hexagon super-lattice structure oscillating with time. The device comprises the vacuum tank; a humidification spraying device and the discharge device are arranged in the vacuum tank; a spraying nozzle of the humidification spraying device corresponds to the discharge gas of the discharge device. Bythe plasma photonic crystal generated by the method, the forbidden band position and the width of the plasma photonic crystal can be continuously changed with time without changing the discharge condition.

Description

technical field [0001] The invention relates to a method and a device for generating a plasma photonic crystal with time-oscillation, and belongs to the field of plasma application technology and the field of optics. 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 a 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 on the refractive ...
