Electrostriction temporal shift of laser pulses in optical fibres

A model is proposed which describes the electrostriction temporal shift of laser pulses in their high-frequency train propagating in an optical fibre. The validity of the model is confirmed by good agreement of its predictions with the results of studies of relative temporal shifts in the high-frequency train of optical solitons known from the literature. The model predicts the possibility of a substantial reduction of temporal shifts in the data pulse train in fibreoptic links composed of fibres with different signs of dispersion. For comparatively low pulse repetition rates (less than 500 MHz), the oscillating dependence of the relative temporal shift of pulses on the data transmission rate is found.
