Optically controlled tunable dispersion compensators based on pumped fiber gratings

摘要

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 psm and also from -600 to -950 psm in the experiment.
