Informatique photonique
L'informatique photonique utilise des technologies basées sur la lumière pour un traitement des données efficace et à grande vitesse.

L'informatique photonique utilise des composants à base de lumière pour effectuer des calculs à grande vitesse et à faible consommation d'énergie. La photonique sur silicium permet d'intégrer des modulateurs optiques, des détecteurs et des guides d'ondes sur une seule puce. Les interconnexions optiques réduisent la latence et les goulets d'étranglement de la bande passante dans le transfert de données. L'optique non linéaire et les guides d'ondes à cristaux photoniques facilitent la commutation tout-optique et le transfert de données. traitement du signal. Les réseaux neuronaux photoniques et les cœurs tensoriels accélèrent les charges de travail liées à l'apprentissage automatique. Point quantique Les lasers et les sources laser intégrées fournissent une lumière cohérente pour le calcul. Les portes logiques optiques et les résonateurs mettent en œuvre les unités de traitement fondamentales. Le multiplexage par répartition en longueur d'onde améliore le parallélisme dans les canaux de données. Les progrès réalisés dans la fabrication de dispositifs photoniques permettent de mettre en place des architectures évolutives pour les futurs systèmes informatiques.
