Abstract :
We demonstrate dispersion slope compensation for three 10-Gbit/s wavelength-division-multiplexing (WDM) channels using a sampled nonlinearly chirped fiber Bragg grating (FBG) in a dispersion-managed transmission system. The replicated wavelength bands of the sampled FBG have a different wavelength separation than the WDM channels, causing each channel to experience a different dispersion compensation that can be tuned upon stretching of the FBG. We achieve significant power penalty reduction for all three channels using our dispersion-slope-compensation method with a tunable amount of dispersion over 900 and 1200 km fiber links.
