Transverse Brillouin effect produced by electrostriction in optical fibersand its impact on soliton transmission systems

Large radial gradient of light intensity in single-mode fibers leads to exc itation of transverse acoustic waves through electrostriction mechanism. Th e nanosecond range for the acoustic effect introduces a time-dependent inde x evolution for the optical pulses following and results in an additional t emporal shift. The dynamic frequency shift of optical pulses in optical fib ers is evaluated by a time-domain resolution technique using copropagated p ump and probe signals arrangement. Complete electrostrictive response measu rements including excitation of pure radial and mixed torsional-radial acou stic modes are presented. In a second time, the acoustic effect is incorpor ated in the nonlinear Schrodinger equation as a perturbative term. We have investigated the evolution of timing jitter, taking into account both the G ordon-Haus and the acoustic interaction contributions for different dispers ion management soliton system configurations in order to evaluate the induc ed penalties.
