Abstract

We propose and demonstrate a novel optically tunable dynamic dispersion-compensation device with coupled-cavity etalon structure. Experimentally, it was achieved with an all-fiber coupled-cavity etalon made in an $\mathrm{Er}∕\mathrm{Yb}$ codoped fiber pumped by a $980\text{-}\mathrm{nm}$ laser diode. The dispersion was tuned from $-300\text{to}+400\mathrm{ps}∕\mathrm{nm}$ in the experiment. The potential advantages of such optically tunable dispersion compensators include fast response time and remotely controllable operation.
