Abstract :
We demonstrate a novel technique for tunable dispersion slope compensation that relies on a single nonchannelized chirped fiber Bragg grating (FBG). This grating is unique in that it is written such that the time delay as a function of wavelength is a third-order profile that covers several WDM channels over a continuous bandwidth of many nanometers. The dispersion range provided by the grating for the WDM channels can be up to 400 ps/nm, enabling dispersion slope compensation.
