1. method that is used for producd fibers matter element (F0), it is characterized in that this method comprises:

  • i) form assembly (E) by surrounding the first (C) that forms by vitreous material with second portion (G) with the inside (P1) that surrounds by outside (P2);

    Described assembly (E) then along the longitudinal ii) stretches, reduce its at least one lateral dimension simultaneously to increase its longitudinal size, select described increase and reduce, make described second portion (G) can along with the direction of vertical perpendicular of the assembly of drawn selectively wavelength-filtered fall into the photon of at least one selected band, wherein, described outside (P2) is designed to light filter (FE) precursor, after described assembly (E) is stretched, this light filter (FE) precursor constitutes light filter, comes reflection wavelength to fall into the photon of described selected band.
