Abstract

The invention provides a method for producing a three-dimensional plasma photon crystal. The method comprises the steps that two water electrodes are installed in a vacuum reaction chamber, three layers of laminated glass are arranged between the water electrodes, and a discharge gap with a cavity cross section of an H-shaped structure is formed in the three layers of glass; air and argon mixed gas is injected into the vacuum reaction chamber, gas content, gas pressure, discharge frequency and discharge pressure are adjusted, and the three-dimensional plasma photon crystal consisting of straight and oblique plasma photon crystals can be produced at the H-shaped discharge gap. The oblique plasma photon crystal is found for the first time. The energy band structure and band gap width of the three-dimensional plasma photon crystal consisting of straight and oblique plasma photon crystals are richer and can be controlled in a tuned mode, the research blank of the three-dimensional plasma photon crystal is filled, wave bands of modulation light beams are further widened, and diversified, convenient and efficient light beam modulation is achieved.

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 three-dimensional plasma photonic crystal. Background technique [0002] As a new type of photonic crystal, plasmonic photonic crystal is a periodic structure formed by the periodic distribution of the density of plasma itself or interlaced with other dielectric materials. It not only has the characteristics of conventional photonic crystals such as photon band gap and photon localization, but also has special properties such as anomalous refraction and special frequency band relationship due to the existence of plasma (dispersion characteristics and dissipation characteristics). In particular, by adjusting the external drive, changing the time or space parameters of the plasma, the control of the energy band structure of the plasma photonic crystal can be realized, and then the propagation of electromagnetic waves of di...
