CHARACTERISTICS OF SOLITON PULSES IN AN OPTICAL-FIBER WITH A PERIODICALLY MODULATED CORE DIAMETER

We use numerical modeling to study the dynamics of propagation of a co upled pair of two-soliton pulses and a one-soliton pulse with a weakly perturbed amplitude in an optical fiber where the diameter of the cor e is periodically modulated. The mathematical model includes variation s in dispersion characteristics and the effective area of the fundamen tal mode of a fiber. The theoretical possibility of producing a sequen ce of soliton pulses with the required spectral, phase, and amplitude characteristics in the considered waveguide is demonstrated. We can co ntrol the number of pulses in such sequences and parameters of pulses by varying the phase and the amplitude of the input signal.
