An optical waveguide device includes a plurality of optical waveguides propagating therethrough a signal beam, and a plurality of optical sub-waveguides connected to the plurality of optical waveguides respectively, applying an excessive loss to the signal beam by branching a partial beam of the signal beam. A dynamic range and a tolerance in an amount of the excessive loss is adjusted by adjusting widths of the plurality of optical sub-waveguides with respect to the plurality of optical waveguides, and the amount of the excessive loss applied to the signal beam are adjusted by adjusting an angle connecting each of the plurality of optical sub-waveguides with respect to each of the plurality of optical waveguides.
L'invention en question est un dispositif de guides d'ondes optiques qui comprend de nombreux guides d'ondes se propageant par un faisceau signal, ainsi que plusieurs sous-guides d'ondes optiques raccordés aux nombreux guides d'ondes optiques, respectivement; le principe de fonctionnement consiste à appliquer une perte excessive au faisceau signal par le raccordement d'un faisceau partiel au faisceau signal. Une portée dynamique et une tolérance dans le degré de la perte excessive sont réglées en ajustant les largeurs des nombreux sous-guides d'ondes optiques par rapport aux nombreux guides d'ondes optiques, et le degré de perte excessive appliquée au faisceau signal est réglé en ajustant un angle entre chacun des nombreux sous- guides d'ondes optiques et chacun des nombreux guides d'ondes optiques.
