Silicon Photonics
Integrating photonic and electronic functions on silicon to power next-generation AI, cloud, and communications networks.
OverviewSilicon photonics combines optical components—including waveguides, modulators, photodetectors, and multiplexers—with CMOS manufacturing processes to create high-performance, low-cost optical interconnects. The technology enables faster data movement while reducing power consumption compared with traditional electrical signaling.
ApplicationsSilicon photonics is widely deployed in hyperscale data centers, AI clusters, high-performance computing, telecom transport, data center interconnect (DCI), and increasingly in advanced chip-to-chip and package-level optical communications.
