摘要

mikrostrukturalny fiber with selectively enlarged spaces with reduced coefficient of refractive index, especially for generation of nonlinear effects and measurement of stress placed pieru015bcieniowo around the core (1) surrounded by a mantle of spaces close to the cross-section and reduced coefficient of refractive index.especially to the generation of nonlinear effects and stress measurement made of glass, preferably silica glass or polymer, in which the spaces located around the core are filled with gas pieru015bcieniowo favourably, favourably air or liquid or polymer and placed s and in the lymph heksagonalnej grid distance between grid nodes equal to the fixed network.in which around jednomodowego core are placed at least three rings containing spaces with reduced coefficient of light gas filled or liquid or a polymer in which the diameter of the space of reduced coefficient of t wiatu0142a in at least one ring is increased, so that is less than twice the fixed network.and all diameters plus space of reduced coefficient of diameter (d) are the same, not plus space of reduced diameters (d) have similar refractive index, and less from the fixed network diameter and diameter ratio (d) powiu0119 mortality area to a fixed network is contained in the range of 0.30 to 0.45.
