Title (EN) WAVELENGTH SELECTIVE OPTICAL DEVICES
(FR) DISPOSITIFS OPTIQUES SELECTIFS EN LONGUEURS D'ONDES
Abstract:
(EN) Wavelength selective devices and subsystems having various applications in the field of optical communications are disclosed. These devices and subsystems are composed of bidirectional grating assisted mode couplers (9). The high add/drop efficiency and low loss of this coupler enable low loss wavelength selective elements such as optical switches (62), amplifiers (63), routers (5), and sources to be fabricated. The grating assisted mode coupler (23) can be wavelength tuned by modifying the optical properties of the coupler interaction region. A programmable, wavelength selective router (5) composed of multiple grating assisted mode couplers is also disclosed.
(FR) L'invention concerne des dispositifs et des sous-systèmes sélectifs en longueurs d'ondes ayant diverses applications dans le domaine des communications optiques. Les dispositifs et les sous-systèmes en question sont équipés de coupleurs (9) à réseau de diffraction en mode bidirectionnel. La grande efficacité d'insertion-extraction et les faibles pertes de ce type de coupleur permettent de fabriquer des éléments sélectifs en longueurs d'ondes à faible perte tels que, par exemple: interrupteurs (62), amplificateurs (63), routeurs (5) et sources optiques. En modifiant les propriétés optiques de la zone d'interaction du coupleur, on peut régler en longueur d'onde le coupleur (23) considéré. On décrit par ailleurs un routeur (5) programmable sélectifs en longueurs d'ondes doté de plusieurs coupleurs de ce type.
