Silicon Photonics

Silicon Photonics
Integrating photonic and electronic functions on silicon to power next-generation AI, cloud, and communications networks.
Overview Silicon 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.
Applications Silicon 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.
