Understanding the Photonics & Silicon Photonics Sector
Research & Analysis · Equities · Photonics & Silicon Photonics · August 2026
The photonics and silicon photonics sector is emerging as a critical component of next-generation computing infrastructure, driven by the rapid expansion of artificial intelligence (AI), hyperscale data centers, and high-speed connectivity. As conventional copper-based interconnects face increasing limitations in bandwidth, energy efficiency, and data transmission, optical technologies are becoming essential for supporting the growing computational demands of AI. Silicon photonics, which integrates optical components into semiconductor chips, offers a scalable approach to transmitting data using light rather than electrical signals.
The global photonics market was estimated at approximately $989 billion in 2025 and is projected to reach $1.84 trillion by 2036, representing an annual growth rate of approximately 5.8%. Within this broader industry, silicon photonics represents a particularly high-growth segment, with revenue projected to increase from approximately $3 billion in 2025 to $10 billion by 2030, implying annualized growth of roughly 27%. The expansion of AI infrastructure, rising optical content per data center, and advancements in co-packaged optics are expected to support this growth.
