Abstract

The paper analyzes a modal structure of the guided modes in photonic liquid crystal fibers (PLCFs) by using numerical methods and presents experimental verification of the theoretical results. The theoretical analyses is based on numerical methods applied to find solution of the Helmholtz equation that describes possible forms of modal field propagating inside photonic crystal fiber (PCF) of defined geometry, as well as optical parameters. Numerical calculations based on the Finite Difference method were preformed for two different kinds of digitization of the PLCF structure (i.e. for using square and triangular lattice). Several boundary conditions applied in the case of analyzed lattices such as: constant, Dirichlet and semi-transparent condition were discussed. Input parameters of preformed simulations can be divided into two groups: physical and purely numerical. Physical parameters are: wavelength, number of capillaries, and spatial distribution of refractive index (in cross section of fiber surface). Numerical parameters are: type of used lattice, resolution of the lattice and the boundary condition. Numerical output is the value of effective refractive index and additionally shape of propagating mode field. In experimental part the measurements of numerical aperture (NA) were done in the way to find effective refractive indices of modes propagating in PCFs and PLCFs.
