CA 2291054
A method of creating an optical filter for selectively filtering an optical signal transmitted through said filter, said method comprising: constructing a Bragg grating in an optical element (2) coupled (3, 4) to an optical pathway (8) for the transmission of said optical signal to suppress background radiation; and adjusting (6, 7) said coupling so as to produce a selective transmission spectrum in accordance with predetermined requirements.
La technique visant à créer un filtre optique permettant un filtrage sélectif d'un signal optique transitant par ledit filtre consiste à monter un réseau de Bragg dans un élément optique (2) couplé (3, 4) à un trajet optique (8) servant à la transmission dudit signal optique pour supprimer le rayonnement de fond et à adapter (6, 7) ce couplage de manière à obtenir un spectre de transmission sélectif et ce, en conformité avec des exigences prédéfinies.
