Calcolo fotonico
L'informatica fotonica utilizza la luce tecnologie per un'elaborazione efficiente e ad alta velocità dei dati.

L'informatica fotonica sfrutta i componenti basati sulla luce per eseguire calcoli ad alta velocità e a basso consumo energetico. La fotonica del silicio consente l'integrazione di modulatori ottici, rivelatori e guide d'onda su un singolo chip. Le interconnessioni ottiche riducono i colli di bottiglia della latenza e della larghezza di banda nel trasferimento dei dati. L'ottica non lineare e le guide d'onda a cristalli fotonici facilitano la commutazione e la commutazione completamente ottica. elaborazione del segnale. Le reti neurali fotoniche e i core tensoriali accelerano i carichi di lavoro dell'apprendimento automatico. Punto quantico I laser e le sorgenti laser integrate forniscono luce coerente per il calcolo. Le porte logiche ottiche e i risonatori implementano le unità di elaborazione fondamentali. Il multiplexing a divisione di lunghezza d'onda migliora il parallelismo nei canali di dati. I progressi nella fabbricazione di dispositivi fotonici supportano architetture scalabili per i futuri sistemi di elaborazione.
