ABSTRACT:
An optical fiber wavelength converter inputs signal light and pumping light into an end of the highly nonlinear optical fiber to obtain converted light of the signal light from the other end of the highly nonlinear optical fiber. In the optical fiber wavelength converter, a wavelength λp of the pumping light is set within a range from λ0−1 nanometers to λ0+1 nanometers, where λ0is a zero-dispersion wavelength of the highly nonlinear optical fiber, an absolute value of a dispersion slope of the highly nonlinear optical fiber with the wavelength λp is not more than 0.02 ps
m2/km, a nonlinear coefficient γ of the highly nonlinear optical fiber with the wavelength λp is not less than 10/W/km, and a change in a conversion bandwidth D defined as D=|λp−λs2| is not more than 30 percent at variable environmental temperatures ranging from 0° C to 40° C.
