A novel sliding-frequency guiding filter for soliton transmission

Abstract

The Gordon-Haus effect can be substantially reduced by using the sliding-frequency guiding filters. However, a long-distance (such as transoceanic) soliton transmission system may require hundreds of these filters operating at slightly different wavelengths from each other. Thus, it would be difficult in practice to produce and install such a large number of these filters all operating at different wavelengths. In this letter, we demonstrate a novel sliding-frequency guiding filter which automatically offsets its peak wavelength from the wavelength of soliton pulses. Thus, these filters can guide the soliton pulses to slightly different wavelengths continuously, although they are made to be identical.
