Photonic computing
Photonic computing utilizes light-based technologies for efficient and high-speed data processing.

A computação fotônica utiliza componentes baseados em luz para realizar cálculos com alta velocidade e baixo consumo de energia. A fotônica de silício permite a integração de moduladores ópticos, detectores e guias de onda em um único chip. As interconexões ópticas reduzem a latência e os gargalos de largura de banda na transferência de dados. A óptica não linear e os guias de onda de cristal fotônico facilitam a comutação totalmente óptica e processamento de sinaisRedes neurais fotônicas e núcleos tensores aceleram cargas de trabalho de aprendizado de máquina. Ponto quântico Lasers e fontes de laser integradas fornecem luz coerente para computação. Portas lógicas ópticas e ressonadores implementam unidades de processamento fundamentais. A multiplexação por divisão de comprimento de onda aprimora o paralelismo em canais de dados. Avanços na fabricação de dispositivos fotônicos suportam arquiteturas escaláveis ​​para futuros sistemas de computação.
