Optimal design of tunable parametric wavelength converters based on degenerated four-wave mixing in optical fibers

With the emergency of the dispersion flatten HNL-DSF and PCF, the one-pump parametric wavelength converter (PWC) based on degenerate four wave mixing in optical fibers becomes more and more attractive, owing to its low cost, simple structure and wide tunablity. In this paper it is proved that using a media fiber with appropriate zero dispersion wavelength, the tuning range of the one-pump PWC can be maximized. The maximal tuning range is proportional to the cube root of the product of the pump power and fiber nonlinear coefficient.
