Title
(EN) OPTICAL PRE-AMPLIFIER
(FR) PREAMPLIFICATEUR OPTIQUE
Abstract
(EN)
An optical pre-amplifier for amplifying optical signals which have been transmitted via a dispersive optical transmission link, comprises a chirped Bragg grating noise filter. The filter also acts as a dispersion compensating filter, with the dispersion of the chirped Bragg grating noise filter acting against the dispersion of the optical transmission link.
(FR)
La présente invention concerne un préamplificateur optique qui amplifie les signaux optiques transmis par l'intermédiaire d'un chaînon de voie de transmission optique dispersive, comportant un filtre de bruit à réseau de Bragg pulsé. Le filtre sert aussi de filtre compensateur de dispersion, le filtre de bruit à réseau de Bragg pulsé agissant contre la dispersion du chaînon de voie de transmission optique.
