DATA & FILE OVERVIEW
--------------------

The ZIP file includes results of numerical simulation used to generate Figures 1, 2 and 5-7. Details of indivual files are given below. Design 1 and 2 refer to multi-mode NANF designs described in the publication. All data is stored in CSV (comma separated values) format.

This dataset contains:

-"data.zip"
-->"fig1-data.csv" the number of mode groups required to be guided in a hollow-core fiber to achieve 95 % coupling efficiency for an incident laser beam of a given M^2.
-->"fig2-data.csv" several different modal distributions of laser beams with M^2=3 before and after coupling into a fiber and the total coupling efficiency to a 10 mode fiber as a function of the beam waist ratio (beam waist relative to core radius)
-->"fig5a-data.csv" maximum modal loss across all modes of Design 1 and 2 when straight.
-->"fig5b-data.csv" maximum modal bending loss at 1030 nm across all modes of Designs 1 and 2.
-->"fig5c-data.csv" delivered power after coupling and propagation for a M^2=3 beam incident on Design 1 and a M^2=13 beam incident on Design 2 given constant 35 cm bend.
-->"fig5d-data.csv" maximum leakage loss and the fraction of power in the glass of all mode groups of Design 1 at 1030 nm when straight.
-->"fig6a-data.csv" coupling efficiency and maximum pulse energy before damage for a 10 ns, M^2 = 3 pulse incident on Design 1, varying focus
-->"fig6b-data.csv" coupling efficiency and maximum pulse energy before damage for a 10 ps, M^2 = 13 pulse incident on Design 2, varying focus
-->"fig6c-data.csv" coupling efficiency and maximum pulse energy before damage for a 10 ns, M^2 = 3 pulse incident on Design 1, varying alignment
-->"fig6d-data.csv" coupling efficiency and maximum pulse energy before damage for a 10 ps, M^2 = 13 pulse incident on Design 2, varying alignment
-->"fig7a-data.csv" maximum dispersion parameter, D, as a function of wavelength for Designs 1 and 2
-->"fig7b-data.csv" maximum differential group delay, DGD, as a function of wavelength for Designs 1 and 2
-->"fig7c-data.csv" the DGD of every tenth mode group in Design 2 at 1030 nm
