CA 2276419

A plurality of fiber lasers or amplifiers which share a common pump source. Cost and efficiency improvement of waveguide fiber telecommunications systems are made possible by routing pump laser power through a 1 x N coupler to supply pump light to desired combinations of optical fiber lasers or amplifiers. The design is readily adapted to the use of modules, for example laser modules which have a port for receiving pump light and a port for receiving a wavelength selecting module.

L'invention concerne une pluralité de lasers à fibres ou d'amplificateurs partageant une source de pompage commune. Le coût et l'efficacité de systèmes de télécommunications à fibres à guides d'ondes peuvent être améliorés grâce à l'acheminement de l'énergie d'un laser de pompage par l'intermédiaire d'un coupleur 1 x N en vue d'alimenter en lumière de pompage les combinaisons voulues de lasers à fibres optiques ou d'amplificateurs. La conception est rapide à adapter à l'utilisation des modules, par exemple des modules laser qui ont une entrée permettant de recevoir la lumière de pompage et une entrée permettant de recevoir un module de sélection de longueurs d'ondes.
