Abstract

We propose a novel technique to compensate dispersion adaptively. First, an error is calculated from the waveform of output signal in the time domain. Then a tunable dispersion compensator is controlled toward minimizing the error value by means of steepest-descent method. Transmission experiments and simulations show that the proposed technique can compensate the dispersion quickly for a wide dispersion range
