Abstract
We have fabricated and characterized a tunable dispersion compensator that utilizes a specially designed sampled nonlinearly-chirped FBG which is suitable for WDM channels. The dispersion can be tuned from -200 to -1200 ps/nm. We experimentally demonstrated tunable dispersion compensation using the sampled nonlinearly chirped FBG in a 10-Gb/s WDM system. All three channels achieve BER=10−9 after both 60 km and 120 km of SMF by tuning the dispersion of the grating between -550 and -1100 ps/nm.
