CA 2359387

In a digital optical switch, an input waveguide and two output waveguides form a Y--shaped splitter or switch. Electrodes are positioned on each output waveguide at the junction with the input waveguide. The electrodes extend as narrow strips across the waveguides. The inner edges of the electrodes are curved to form a smooth continuation profile to the signal paths to reduce losses.

Dans un commutateur numérique optique, un guide d'ondes d'entrée et deux guides de sortie forment un répartiteur ou un commutateur en forme de Y. Des électrodes sont placées sur chaque guide d'ondes de sortie à la jonction avec le guide d'ondes d'entrée. Les électrodes s'étendent en bandes étroites à travers les guides d'ondes. Les bords intérieurs des électrodes sont courbés pour former un profil continu comme chemin de signaux afin de réduire les pertes.
