A reduced size multiplexer/demultiplexer component is achieved by tapering of waveguide ends in any of the input, output array, or phase shifting array of waveguides. Cross talk is limited in the tapered region by requiring that each waveguide in a tapered array have a distinct propagation constant.

L'invention concerne la formation d'un composant de multiplexage/démultiplexage de dimension réduite par transition progressive d'extrémités de guides d'ondes dans l'un ou l'autre des réseaux d'entrée, de sortie ou de déphasage de guides d'ondes. On peut limiter une diaphonie dans la partie à transition progressive en exigeant que chaque guide d'onde dans un réseau à transition progressive possède une constante de propagation distincte.
