CA 2311807

An integrated optical circuit formed on an optically conductive substrate having light absorbing means comprising one or more doped areas (1) of the substrate where the doping concentration is greater than that of areas of the substrate forming the optical circuit (2) to absorb stray light in the substrate which is not guided by components of the optical circuit.

La présente invention concerne un circuit optique intégré formé sur un substrat optiquement conducteur comportant des organes photo-absorbants comprenant une ou plusieurs zones dopées (1) du substrat. En l'occurrence, la concentration de dopage est supérieure à celle des zones de substrat formant le circuit optique (2), et ce, de façon à absorber la lumière parasite dans le substrat, sans être guidé par des composants du circuit optique.
