Non-linear fiber resistant to perturbations

[0028]Embodiments of the present invention generally relate to non-linear fibers resistant to perturbations. More specifically, embodiments of the present invention relate to a fiber design that achieves high nonlinearity and a low sensitivity to perturbations in fiber scaling.

[0029]Generally speaking, embodiments of the present invention may be utilized for a wavelength conversion process requiring phase matching with an effective index. As variations in scaling, variations in dispersion near the zero-dispersion wavelength, and variations in the wavelengths of the phase-matched signal and idler, are all proxies for phase matching variations in a sensitivity analysis, embodiments of the present invention may be utilized to create waveguides that are substantially insensitive to such variations.
