Abstract
A new scheme is presented in this letter that, by using double orthogonal pump in a semiconductor fiber ring laser, gives a better solution to improve the conversion efficiency and to deduce noise figure of wavelength converters based on four-wave mixing. The noise figure in this scheme is smaller than normal broad-band orthogonal-pump scheme. Experimental results show nearly flat conversion efficiency and signal-to-noise ratio in a wavelength-shift range of more than 40 nm.Keywords
