Abstract: front page image
(EN)An optical monitor device and method are presented aimed at providing low-loss monitoring of an optical signal confined in an optical guiding structure. An optical resonator structure is placed spatially adjacent to the guiding structure and is optically coupled to the guiding structure, and an optical detector is optically coupled to the resonator structure. The coupling between these elements is such that the coupling of light from the guiding structure to the optical resonator is smaller then the coupling of light from the resonator to the optical detector.
(FR)L'invention concerne un dispositif de contrôle optique et un procédé associé permettant d'obtenir un contrôle à faible perte d'un signal optique confiné dans une structure de guidage optique. Une structure résonante optique est placée adjacente à la structure de guidage et est couplée optiquement à ladite structure de guidage et un détecteur optique est couplé optiquement à cette structure résonante. Le couplage entre ces éléments est tel que le couplage de la lumière de la structure de guidage à la structure résonante optique est inférieur au couplage de la lumière de la structure résonante au détecteur optique.
