Patent

CA 2394004

The fiber optic devices disclosed include fiber optic coupler-isolator combinations. These combinations are especially applicable to fiber optic tapping and pumping arrangements. By integrating such devices into a housed subassembly, enhanced size and design characteristics are achieved. The first coupler (324) may be used for multiplexing a signal and a pump beam whereas the second (354) is used for monitoring. The isolator (318) receives and transmits the light to the couplers via slanted GRIN lenses.

L'invention concerne des dispositifs à fibres optiques comprenant des combinaisons intégrées coupleurs optiques-isolateurs optiques. Ces combinaisons sont utilisées, en particulier, pour les configurations de branchement et de pompage optique. L'intégration de tels dispositifs dans un sous-ensemble enclavé permet l'obtention de caractéristiques de taille et de conception améliorées.
