Design of highly nonlinear bismuth-oxide holey fibres with zero dispersion and enhanced Brillouin suppression

Abstract

We demonstrate that Bi-based holey fibres can achieve the same nonlinear performance as their all solid counterparts, but with greatly improved dispersion control. Longitudinally tapering the structural parameters allows at least a further 13.5 times improvement in the Kerr-to-Brillouin figure-of-merit
