Abstract

We demonstrate optically tunable dispersion compensators based on pumping fiber Bragg gratings made in Er/Yb codoped fiber. The tunable dispersion for a chirped grating and also a uniform-period grating was successfully demonstrated in the experiment. The dispersion of the chirped grating was tuned from 900 to $1990\mathrm{ps}/\mathrm{nm}$ and also from $-600$ to $-950\mathrm{ps}/\mathrm{nm}$ in the experiment.
