[:en]All optical processing of telecommunication signals is advantageous since it is transparent to modulation format and transmission speed. Furthermore, it enables parallel processing of multiple data streams. However, despite numerous laboratory demonstrations, all-optical processing is not used in commercial solutions. One of the major factors limiting its adoption is that it requires high optical powers to perform efficiently. To mitigate that we are working in collaboration with colleagues from the Chemistry Department to develop highly nonlinear waveguides optimised for operation at telecommunication wavelengths. By combining the high level of optical confinement achievable with silicon photonics with novel nonlinear molecules, we want to create compact and efficient integrated all-optical devices.[:fr]Le traitement tout-optique des signaux de t\u00e9l\u00e9communication est avantageux car il est transparent au format de modulation et \u00e0 la vitesse de transmission. De plus, il permet le traitement parall\u00e8le de plusieurs flux de donn\u00e9es. Cependant, en d\u00e9pit de nombreuses d\u00e9monstrations en laboratoire, le traitement tout-optique n’est pas utilis\u00e9 dans les dispositifs commerciaux. L’un des principaux facteurs limitant son adoption est qu’il n\u00e9cessite des puissances optiques \u00e9lev\u00e9es pour fonctionner efficacement. Pour am\u00e9liorer cela, nous travaillons en collaboration avec des coll\u00e8gues du D\u00e9partement de chimie \u00e0 d\u00e9velopper des guides d’onde fortement non-lin\u00e9aires optimis\u00e9s pour fonctionner aux longueurs d’onde utilis\u00e9es en t\u00e9l\u00e9communication. En combinant le haut niveau de confinement optique r\u00e9alisable avec la photonique sur silicium avec de nouvelles mol\u00e9cules non-lin\u00e9aires, nous voulons cr\u00e9er des dispositifs tout-optiques int\u00e9gr\u00e9s compacts et efficaces.[:]<\/p>\n","protected":false},"excerpt":{"rendered":"
