✦ Synopsis
Large radial gradient of light intensity in single-mode fibers leads to excitation of transverse acoustic waves through electrostriction mechanism. The nanosecond range for the acoustic effect introduces a time-dependent index evolution for the optical pulses following and results in an additional temporal shift. The dynamic frequency shift of optical pulses in optical fibers is evaluated by a time-domain resolution technique using copropagated pump and probe signals arrangement. Complete electrostrictive response measurements including excitation of pure radial and mixed torsional᎐radial acoustic modes are presented. In a second time, the acoustic effect is incorporated in the nonlinear Schrodinger equation as a perturbative term.
Ẅe have investigated the evolution of timing jitter, taking into account both the Gordon᎐Haus and the acoustic interaction contributions for different dispersion management soliton system configurations in order to evaluate the induced penalties.
