Abstract
Disclosed is an all waveguide fiber wavelength converter which makes use of modulational instability to convert signal wavelength over a conversion bandwidth while maintaining low pump laser power relative to other wavelength conversion devices such as those which make use of four wave mixing. The device is operated in the anomalous dispersion region of the waveguides and the zero dispersion of the waveguide in which conversion occurs is less than the pump wavelength so that conversion may occur for signal wavelengths above and below the zero dispersion wavelength. Conversion efficiency is in the range of 25 dB to 30 dB.
