Research on HNLF and Broadband Wavelength Converter

In this paper,we use a High Non-Linear Fiber（HNLF）to achieve broadband wavelength conversion.We first introduce the basic principles and parameters of HNLF,and then derive the theory of wavelength conversion based on Four-Wave Mixing（FWM）.Finally,the factors which may have influences on the conversion efficiency are analyzed.The simulations are conducted in the software Optisystem.After optimization of several parameters,we demonstrate a broadband and high-efficiency converter based on HNLF.
