Abstract
The nonlinearity in optical fibres can be enhanced significantly by reducing the effective mode area or by using materials with higher nonlinear-index coefficient (n2). In this paper we combine these two concepts and experimentally demonstrate enhanced Kerr nonlinear effects in tapered highly nonlinear As2Se3 chalcogenide fibre. We taper the fibre to sub-wavelength waist diameter of 1.2 μm and observe enhanced nonlinearity of 63,600 W-1km-1. This is 40,000 times larger than in silica single-mode fibre, owing to the 400 times larger n2 and almost 100 times smaller effective mode area. We also discuss the role of group velocity dispersion in these highly nonlinear fibre tapers.
