Design of low-dispersion fractal photonic crystal fiber
Authors
Abstract:
In this paper, a fractal photonic crystal fiber (F-PCF) based on the 1st iteration of Koch fractal configuration for optical communication systems is presented. Complex structure of fractal shape is build up through replication of a base shape. Nowadays, fractal shapes are used widely in antenna topics and its usage in PCF has not been investigated yet. The purpose of this research is to compare normal photonic crystal fibers (N-PCFs) with F-PCFs through the simulation and optimization procedure based on the finite element method (FEM). The effective mode index of the fundamental mode is found for different PCF structures. In addition, dispersion properties of F-PCF are numerically calculated and compared with N-PCF.

In this paper, We design a novel Hexagonal Lattice photonic crystal fiber (PCF) made of soft glass achieving low confinement loss and low chromatic dispersion through the optimization of the arrangement and diameter of circular air holes. The motivation behind this is to optimize the design parameter of PCF to gain low-flattened chromatic dispersion and low confinement loss at wide wavelength r...

Group-velocity dispersion of birefringent GeAsSe tapered PCF is directly measured over 1900-2300nm range using all-fiber Mach-Zehnder interferometer. We experimentally prove that zero-dispersion wavelength of chalcogenide PCFs can be shifted to thulium/holmium doped silica emission band.

We propose a new type highly birefringent spiral photonic crystal fiber (PCF) for residual dispersion compensation in a wide range of wavelengths. The 2-D finite element method (FEM) with perfectly matched boundary layer (PML) is used for numerical simulation. The arrangement and diameter of circular air holes in the designed PCF has been tuned to offer almost flat dispersion profile with avera...
