1. a method that is used for producd fibers matter element (FO) is characterized in that this method comprises:

  • i) form assembly (E) by surrounding vitreous material first (C) with the second portion (G) with first optical property;

    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 at least some described first optical characteristics of second portion (G) be transformed into second optical characteristics, thus enable 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.
