A method of generating a signal pulse in an optical fiber characterized by dispersion and a refraction index that has a nonlinear regime of operation, the method including generating a sequence of coherent optical pulses (50) each of which has an associated energy; and introducing the sequence of pulses into the optical fiber, wherein the pulses in the sequence of pulses are sufficiently close in spacing so that after traveling a predetermined length down the optical fiber, the pulses of the sequence of pulses overlap and interfere to form an interference pattern, and wherein the associated energy of at least one of the pulses of the sequence of pulses is within the nonlinear regime of the optical fiber.
L'invention concerne un procédé permettant de générer une impulsion de signalisation dans une fibre optique caractérisée par dispersion et un indice de réfraction ayant un régime de fonctionnement non linéaire. Le procédé consiste à produire une séquence d'impulsions optiques cohérentes (50) ayant, chacune, une énergie associée; et à introduire ladite séquence dans la fibre optique. Les impulsions dans ladite séquence sont suffisamment rapprochées de sorte que, après avoir parcouru une longueur prédéterminée le long de la fibre optique, elles se chevauchent et s'interfèrent pour former un motif d'interférences, l'énergie associée d'au moins une impulsion de la séquence d'impulsions se situant à l'intérieur du régime non linéaire de la fibre optique.
