Problems solved by technology

[0004] Prior patents ZL200610102333.0 and ZL201010523218.7 have realized plasmonic photonic crystals with three and four refractive indices by adjusting experimental conditions, but they can only be devices for generating single-layer plasmonic photonic crystals, and single-layer plasmonic crystals The modulation of light by bulk photonic crystals is still very limited in the wavelength range, and because of the single modulation method, it is also limited in application fields and application prospects.

Description

technical field [0001] The invention relates to a plasma application technology and an optical technology, in particular to a device and method for producing double-layer plasma photonic crystals. 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 on the refractive index ratio ...
