Tailoring nonlinearity and dispersion of photonic crystal fibers using hybrid cladding

Abstract

We present a hybrid cladding photonic crystal fiber for shaping high nonlinear and flattened dispersion in a wide range of wavelengths. The new structure adopts hybrid cladding with different pitches, air-holes diameters and air-holes arrayed fashions. The full-vector finite element method with perfectly matched layer is used to investigate the characteristics of the hybrid cladding photonic crystal fiber such as nonlinearity and dispersion properties. The influence of the cladding structure parameters on the nonlinear coefficient and geometric dispersion is analyzed. High nonlinear coefficient and the dispersion properties of fibers are tailored by adjusting the cladding structure parameters. A novel hybrid cladding photonic crystal fiber with high nonlinear coefficient and dispersion flattened which is suited for supercontinuum generation is designed.

Characteristics analysis of extruded elliptical hole photonic crystal fibers with square air-core

“…[14][15][16]. Among these methods, FV-FEM and PWEM which are highly suitable for the analysis of periodic structure with anisotropic perfectly matched boundary layers (PWL) is applied [17,18].…”

Comparative study of fundamental properties of honey comb photonic crystal fiber at 1.55µm wavelength

“…First and second order interpolant basis are provided for each triangular elements. PEC (Perfect electrical conductor) or PML (perfectly matched layer) boundary conditions is employed at computational domain for evaluating total dispersion and confinement loss of proposed PCF [25]. …”

Numerical study of photonic crystal fiber with ultra-flattened chromatic dispersion in anomalous and normal dispersion regimes

“…Other structures have been designed for working in a wide range of wavelengths in the area with zero chromatic dispersion wavelength (ZDW) [5][6][7][8]. The PCF with flattened dispersion in a wide range can be used in a wide field of engineering applications such as wide-band supercontinuum generation, dispersion compensation, ultra-short soliton pulse transmission, optical parametric amplification, wavelength-division multiplexing transmission, pulse reshaping or as a candidate for nonlinear optical processes [6][7][8][9][10][11][12].…”
