CA 2095113

An optical network comprises an erbium-doped silica-based optical fibre (30) having a D-shaped cross-section. The wave-guide carries information signals at 1.53 µm from a signal source (38) and provides amplification to the information signals when pumped by an optical pump source operating at 0.994 µm (36). Optical signals are tapped from the waveguide (30) by means of evanescent couplers (32 and 34). The waveguide (30) provides amplification to at least partially restore tapping loss to the information signal due to the optical taps. The core of the optical waveguide (30) is chosen to substantially minimise the spot size of signals ata the wavelength of the pump source (36) so as to provide preferential extraction of the information signal in order to leave the pump source substantially undisturbed to be able to pump regions of the amplifying waveguide (30) beyond the optical tap.

Réseau optique comprenant une fibre optique à base de silice dopée à l'erbium (30), dont la section est en forme de D. Le guide d'onde achemine des signaux d'information à 1,53 µm provenant d'une source de signaux (38) et les amplifie par pompage au moyen d'une source de pompage optique fonctionnant à 0,994 µm (36). Les signaux optiques sont prélevés du guide d'onde au moyen de coupleurs évanescents (32 et 34). Le guide d'onde (30) assure une amplification suffisante pour compenser au moins la perte de prélèvement du signal d'information due aux prises optiques. Le coeur du guide d'onde optique (30) est choisi de façon à réduire sensiblement le diamètre des points constitués par les signaux à la longueur d'onde de la source de pompage (36). On assure ainsi l'extraction préférentielle du signal d'information afin de laisser la source de pompage essentiellement libre d'obstacles pour le pompage des régions du guide d'onde amplificateur (30) qui sont au-delà de la prise optique.
