摘要
The use of nonlinearly chirped fiber Bragg gratings (FBGs) for tunable dispersion compensation is described. It is experimentally demonstrated that wide dispersion tunability can be accomplished over multiple wavelength division multiplexed (WDM) channels simultaneously in a single device with a similar to10 cm long nonlinearly chirped FBG. Multiple channels are generated in such a short grating by fabricating a periodic superstructure over (sampling) the FBG. Proper design of the sampling also allows one to achieve dispersion slope compensation over broad bandwidth in WDM communication systems.
