%% Optical Fibre Toolbox
% Optical Fibre Toolbox (OFT) provides functions for fast automatic
% calculation of guided modes in simple optical fibres. Developed with
% tapered microfibres (aka nanofibres) in mind. Exact solutions for weak
% and strong guidance cases are provided. Material dispersion is taken into 
% account.

% For authors, revisions see readme.txt.
% For EXAMPLES of use, see tutorial3ls.m and oftDemo.m in the DEMO directory.
%
% Main functions
%   buildModes          - Calculates the modal curves (n_eff vs d or n_eff vs lambda)
%   fibreForPM          - Returns possible phase-matching points for 2nd or 3rd harmonic generation
%   modeField           - Returns the field (E, H) value(s) for the two-layer modes (HE/EH, TE, TM)
%   neff                - Returns n_eff for particular mode and argument value
%
% Plotting functions
