Paper Abstract

To achieve high non-linearity in photonic crystal fibers a high nonlinear coefficient of the glass is required accompanied by high coupling efficiency and flat dispersion profile of the fiber with the specific zero dispersion wavelength. In this paper, we present a deterministic method that allow step-by-step design of photonic crystal fibers with desired zero dispersion wavelength, modality and coupling efficiency due to sequential engineering of geometrical parameters of microstructured fibers with nanostructured cores. The fiber consists of inclusions of low refractive index material, embedded in a host glass of higher refractive index, where a single central micro-rod is omitted. In its place an additional nano-inclusion is located of a given diameter. The choice of the glass determines the nonlinear coefficient of the fiber and fabrication possibilities as well. Zero dispersion wavelength is varied by the change of the lattice constant of the cladding. High filling factor in the cladding leads to a large number of propagating high order modes, which can be selectively cut off, when the filling factor of the outer part of the cladding is reduced. The diameter of the nano-inclusion in the core is responsible for the fundamental mode area, which influences directly the coupling efficiency. Several designed structures were modeled numerically and developed to confirm the design method.
