Abstract :
In this paper the propagation properties of microstructured optical fiber with 12-fold quasicrystal lattice of air-holes in a silica matrix have been studied for the first time. Lattices with different hole diameters were considered and curves for the effective index, dispersion and effective area were calculated by a finite element code. The dispersion properties of quasicrystal fibers were compared to that of microstructured fibers with triangular lattice of holes. For dispersion compensation purpose it is proposed a modified 12-fold microstructured quasicrystal fiber with a concentric dual-core structure. With the dual-core design high negative dispersion values ~-40,000 ps/(nm km) could be reached for the wavelength around 1550 nm.
