Abstract
We propose a new technique to reduce the influence of timing jitter without increasing the intersymbol interference by utilizing Kerr nonlinearity in normal dispersion fiber. We carried out numerical simulations of 10 Gb/s soliton transmission and confirmed that the proposed method is more effective than the conventional RZ receiver with a Bessel-Thompson filter in reducing the influence of Gordon-Haus timing jitter. We also employed this technique to the 10 Gb/s optical soliton pulses transmitted at 16, 000km in a sliding frequency recirculating loop. The phase and amplitude margins obtained with the proposed method were 18 % and 67 % wider than that with the lowpass filter with 7.5 GHz bandwidth.
