Silicon Photonics Market Size

The global silicon photonics market was estimated at USD 1.8 billion in 2025. The market is expected to grow from USD 2.3 billion in 2026 to USD 7 billion in 2031 and USD 17.8 billion by 2035, at a CAGR of 25.3% during the forecast period of 2026–2035.

• Hyperscale data centers are expanding to meet the needs of the growing cloud workloads and the growing need to store data. This expansion is driving the need for high-bandwidth and energy-efficient optical links. Compared to copper, silicon photonics is lower in latency, consumes less energy, and is more power-efficient. This is becoming more critical to the operation of highly power-demanding (multi-gigawatt) data center campuses and to the operation of denser and more powerful (multi-gig) servers. For instance, in December 2024, the U.S. Department of Energy predicted U.S. data center electricity demand to more than double, maybe even triple, by 2028, reaching 6.7-12% of the total U.S. electricity demand.  This sheds more light on the need for more efficient silicon-photonics-based interconnects.
   
• AI/ML workloads involve huge parallel processing and extremely high, possibly unprecedented, data-transfer rates between GPUs. Electrical connections cannot support this efficiently, making the use of optical silicon interfaces necessary for high-bandwidth and low-latency connections between GPUs in a training cluster. Their optical I/O interfaces allow for the scalable adoption of next-generation supercomputers for AI. For instance, in October 2025, it was reported by the U.S. Federal Reserve that the U.S. accounts for 74% of global high-end AI compute capacity-a result of rapid GPU-cluster expansion that accelerates demand for silicon-photonics-enabled optical connectivity.
   
• Global telecom operators are upgrading the transport, metro, and fronthaul networks in order to meet the increasing 5G traffic and get ready for early 6G architectures. These upgrades require high-capacity coherent optics in compact form factors, and position silicon photonics as a cost-efficient solution for scaling bandwidth while simultaneously improving network power efficiency. For instance, in November 2024, the International Telecommunication Union said that 5G global coverage reached 51% of the world's population, while driving accelerated investment in optical infrastructure using silicon-photonics-based modules.
   
• Based on components, the global silicon photonics market is segmented into active, and passive. The increasing expansion of fibre backbone and deployment of 5G infrastructures drives the demand for active silicon-photonics which is critical to high speed optical interconnects and switching. According to the OECD, fibre is likely to dominate fixed broadband networks, making up 44.6% of all subscriptions by 2024. This transition from legacy copper infrastructure accelerates the adoption of active photonics technologies.

• Manufacturers are increasingly adopting co-packaged optics to address bandwidth and power constraints in hyperscale data centers. By integrating optical engines directly with switching ASICs, companies achieve higher port density, reduced latency, and greater energy efficiency. This development underlines a more general trend within the industry toward scalable, AI-ready infrastructure; as such, co-packaging optics presents vendors with opportunities to lead through differentiated packaging solutions and high performance PICs. Between 2023 and 2028, CPO design pilots will be running, with early deployment expected in 2024–2025. Commercial deployment will accelerate between 2026 and 2028, with hyperscale data centers standardizing co-packaged optics for the next wave of networking. Suppliers need to scale production and improve yield optimization processes.
   
• Hybrid integration of III-V lasers into silicon wafers is increasingly being implemented by manufacturers to boost performance and decrease costs. In turn, this will drive the development of high-speed transceivers and modulators for a variety of telecom and data center applications. Wafer-level bonding and thermal management are among the strategic investments that manufacturers are making to competitively differentiate their products and supply scalable, high-reliability silicon photonics products. Initial pilots of the hybrid integration started during 2024-2025. By 2027, the volume manufacturing of hybrid integration is expected to gain pace, and leading manufacturers are likely to commercially supply hybrid-integrated silicon photonics products that would drive wider adoption across data centers and telecom networks.
