Abstract

Abstract: We propose an index profiled, highly nonlinear ultra-flattened dispersion fibre (HN-UFF) with appreciable values of fibre parameters such as dispersion, dispersion slope, effective area, nonlinearity, bending loss and splice loss. The designed fibre has normal zero flattened dispersion over S, C, L, U bands and extends up to . The maximum dispersion variation observed for this fibre is as low as over the optical fibre transmission spectrum. This fibre also has two zero dispersion wavelengths at 1.487 and and the respective dispersion slopes are 0.02476 and . The fibre has a very low ITU-T cutoff wavelength of and a virtuous nonlinear coefficient of . The wide spectrum of zero flattened dispersion and a good nonlinear coefficient make the designed fibre very promising for different nonlinear optical signal processing applications.
