[:en]In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology that enables multiple channels to travel in a single optical fiber, which increases the capacity of the link. In order to move toward even higher capacity the mechanisms of WDM optical transmission need to change. The concept of super channels, where several optical carriers are combined to provide the desired capacity, is an evolution in WDM which promises an effective solution to the challenges posed by internet growth. However, super channels have a varying bandwidth, which creates new challenges for switch fabrics. We are aiming to design bandwidth-tunable optical switches that will be able to efficiently handle super channels in optical telecommunication networks.[:fr]Les t\u00e9l\u00e9communications optiques utilisent le multiplexage en longueur d\u2019onde pour transmettre plusieurs canaux simultan\u00e9ment et ainsi augmenter la capacit\u00e9 des liens. Cependant pour r\u00e9ussir \u00e0 r\u00e9pondre \u00e0 la demande toujours croissante, on se dirige pr\u00e9sentement vers une r\u00e9organisation de la bande passante en <>. Ces supers canaux combinent un nombre variable d\u2019ondes porteuses afin de fournir la capacit\u00e9 de transf\u00e8re d\u00e9sir\u00e9e. Les supers canaux ont donc une bande passante variable ce qui am\u00e8ne de nouveaux d\u00e9fis pour la commutation optique. Nous travaillons \u00e0 concevoir un commutateur optique int\u00e9gr\u00e9 capable d\u2019ajuster sa bande passante afin de permettre une utilisation efficace des supers canaux.[:]<\/p>\n","protected":false},"excerpt":{"rendered":"
