Patent

CA 2412395

A wavelength-selective optical device for coupling of light at predetermined wavelength from one optical fiber waveguide to another using at least two gratings and cladding-mode assisted coupling is disclosed. The transfer of light is performed using intermediate coupling to one or more cladding mode of the waveguides, In the case when the fibers have physically different claddings, an arrangement for transfer of light from one cladding to another is required. The disclosed coupler has no back-reflection, small insertion loss, and very high channel isolation. The device can be used in wavelength- division multiplexing networks.

L'invention porte sur un dispositif optique sélecteur de longueurs d'onde et assurant le couplage de lumière de longueurs d'onde données entre deux guides d'ondes à fibre optique à l'aide d'au moins deux réseaux et d'un coupleur en mode gaine. Le transfert de lumière se fait au moyen d'un couplage intermédiqire entre un ou plusieurs modes gaine des guides d'ondes. Dans le cas de fibres présentant des gaines de type différent, on doit prévoir un dispositif de transfert de la lumière d'une gaine à l'autre. Le coupleur de l'invention, qui présente une absence de rétroréflexion, de faibles pertes d'insertion, et une très bonne isolation entre canaux, peut servir dans les réseaux à division des longueurs d'onde par multiplexage.
