Abstract :
We report a novel tunable dispersion compensator (TDC) based on all-fiber distributed Gires-Tournois etalons (DGTE), which is formed by overlapped chirped fiber gratings. Two DGTEs of opposite dispersion slope work together to generate a tunable periodical dispersion profile. The demonstrated TDCs have the advantages of multichannel operation, extremely low group-delay ripple, low loss, and low cost.
