Notes

Using a step-index model for this fibre is likely to be inappropriate. The core diameter, NA, and n2 were chosen for the best match to the specified values for the effective mode area, dispersion at 1550 nm, and the nonlinear coefficient, and most likely are not representative (or even sensible) values for this fibre type.

The specified values are: effective area: 12.5 square microns D(1550 nm): 2 ps/(nm km) nonlinear coefficient: 10.7 1/(W km)

The model values are: effective area: 12.73 square microns D(1550 nm): 2.37 ps/(nm km) nonlinear coefficient: 10.83 1/(W km)

Feehan, et al., “Limits of coherent supercontinuum generation in normal dispersion fibres”, J. Opt. Soc. Am. B 34(4), pp 764-775 (2017).

photonic_crystal_passive_fibre with default parameters which provide fibre properties matching NKT femtoWHITE 800.

Parameters:

grid (pyLaserPulse.grid.grid object)
length (float) – Fibre length.
beat_length (float) – Polarization beat length in m
tol (float) – Tolerance for propagation integration error
n2 (float) – Nonlinear index in m^2 / W. Default value is 2.3e-20 m^2/W. Lower than common values for fused silica at 800 nm, but matches the specified nonlinear parameter.

Notes

The hole pitch (1.339e-6 m) and ratio of the hole diameter with respect to the pitch (0.635) were found using the Nelder Mead algorithm to minimize the difference between the calculated dispersion profile and that shown on the femtoWHITE 800 specification sheet. These values give a good match between 600 nm to 1000 nm and accurately reproduce the first ZDW wavelength of ~750 nm, but DO NOT reproduce the second ZDW wavelength of ~1260 nm that is specified on the data sheet but not shown in the dispersion plot given by NKT.
