Paper Abstract

The results of development of photonic crystal (microstructured, holey) fibers with large (12-35 μm) core are presented. Firstly, large core was comprised by substitution of 7 central holes in the triangular cladding lattice for the glass rod. In another method the core was shifted from the central position by one step of a lattice. In the third type of presented fibers so-called circular core was surrounded by 3 rings of holes; each of rings has contained 12 holes. Listed methods ensure improvement of the fundamental mode confinement in the fiber core. The investigations of modal consistence and resistance of the fundamental mode to bend are provided. Varying the dimensions of holes in the cladding it is possible to make the attenuation of higher order mode considerably stronger than the fundamental one. The fiber supports the single-mode regime, differs from conventional microstructured fibers by high resistance to bend and possesses an expanded operating spectral area.
