| Abstract: | An apodization chirp optical fiber grating (OFG) is fabricated by scanning method. This OFG is 13.5 cm long with 0.447 nm bandwidth and its reflectivity is flatness with ripple coefficient less than 1 dB, while its ripple coefficient of time delay is less than 20 ps. The dispersion of 200 km G.652 optical fiber is compensated by the grating, and more than 98% dispersion is compensated (the original pulse width is 36.78 ps, after compensation the pulse width is 37.23 ps). \{ |
