Description

technical field [0001] The invention relates to the research field of manufacturing special optical fibers, in particular to a filter optical fiber based on an adjustable colloidal photonic crystal and a preparation method thereof. Background technique [0002] Colloidal crystals are a class of substances with a two-dimensional or three-dimensional ordered structure formed by the assembly of one or more monodisperse colloidal particles (inorganic or organic, with a scale of micron or submicron). Colloidal crystals are also called colloidal photonic crystals because the long-range orderly arrangement of colloidal particles creates a photonic band gap in colloidal crystals. Usually, the diffraction peak position of colloidal crystals follows the Bragg diffraction formula, that is, mλ=2ndsinθ, where m is the diffraction order, λ is the diffraction wavelength, n is the average refractive index of colloidal crystals, d is the lattice spacing of colloidal crystals, and θ is incid...
