Title (EN) INTEGRATED MODE CONVERTER AND MULTIPLEXER
(FR) CONVERTISSEUR ET MULTIPLEXEUR DE MODE INTÉGRÉS
Abstract:
(EN) An integrated mode converter and multiplexer (/demultiplexer) is disclosed, which combines a multimode interference coupler (100), at least one phase-shifter (200) and a symmetrical Y-junction (300). The dispersion of the multimode interference coupler (100) is engineered through subwavelength structures in order to achieve a very wide bandwidth. Several phase-shifter (200) topologies for further bandwidth enhancement are disclosed, as well as architectures for multiplexing a greater number of optical modes.
(FR) La présente invention concerne un convertisseur et un multiplexeur (/démultiplexeur) de mode intégrés, qui combinent un coupleur d'interférence multimode (100), au moins un déphaseur (200) et une jonction en Y symétrique (300). La dispersion du coupleur d'interférence multimode (100) est modifiée par l'intermédiaire de structures de sous-longueur d'onde afin d'obtenir une bande passante très large. L'invention concerne également plusieurs topologies de déphaseur (200) destinées à une amélioration de bande passante supplémentaire, ainsi que des architectures permettant de multiplexer un plus grand nombre de modes optiques.
