Abstract:
The maximum rate of signal transmission through nonlinear optical fibres has been obtained as a function of fibre length and signal parameters by numerically solving a nonlinear Schrodinger equation describing the evolution of the envelope of intense short pulses in the waveguide. The optimal pulse durations have been determined as functions of the coefficient of nonlinearity, transmission length, and shape and power of pulse signals. The behaviour of soliton-like pulses and Gaussian pulse shapes has been compared from the standpoint of transmission capacity in nonlinear optical fibre communication channels.
