A unitary dispersion managed waveguide fiber with distributed amplification and a system incorporating the waveguide fiber are disclosed. Total dispersion along the waveguide fiber changes from positive to negative along the length of the waveguide over a transmission wavelength range. Distributed amplification is provided by stimulated emission of a dilute concentration of a rare earth dopant in the waveguide, by Raman effects or by both.
La présente invention concerne une fibre-guide d'ondes unitaire gérée par dispersion avec amplification distribuée et un système intégrant la fibre-guide d'ondes. Le long de la fibre-guide d'ondes, la dispersion totale passe du positif au négatif sur une plage de longueur d'ondes de transmission. L'amplification distribuée s'obtient par émission d'une concentration diluée d'un dopant à base de terre rare dans le guide d'ondes, par effets à diffusion de Raman ou par les deux à la fois.
