Second zero dispersion wavelength measurement through soliton self-frequency shift compensation in suspended core fibre

A simple experimental technique to evaluate the second zero dispersion wavelength of very small core microstructured fibres is described. Based on the effect of soliton self-frequency shift and its subsequent compensation in the vicinity of the second zero dispersion, the proposed method is applied to both standard and suspended core microstructured fibres by simply measuring the frequency stabilised soliton spectrum, avoiding any calculation and knowledge of any experimental parameters.
