A new design of a highly nonlinear dispersion-shifted fiber (HNDSF) with an effective area of 9.3μm2 is presented. The three-dimensional beam propagation method combined with the Gaussian approximation method is used to analyze the new HNDSF. This innovative HNDSF has a unique triple-cladding structure that can offer not only a large nonlinear coefficient but also low attenuation, low splicing, and bending losses. It is a suitable candidate to implement an all-fiber wavelength converter by four-wave mixing.
