Silicon Photonics Chip: The Foundry Battle Heats Up
Discover how silicon photonics chip foundry services are becoming the battleground for AI dominance. Global giants like TSMC, Intel, and Tower Semiconductor are racing to meet explosive demand.
Amid the wave of AI large models iterating toward hundreds of billions and trillions of parameters, computing power demand has experienced an exponential surge. At the same time, the high-speed interconnect bottleneck in data centers has become the critical constraint hindering breakthroughs in AI performance.
Traditional electrical signal transmission is increasingly limited by energy consumption and distance bottlenecks, making it difficult to support the massive data traffic required for AI model training. As transmission rates break through 400 Gbps and evolve toward 800 Gbps or even 1.6 Tbps, the physical properties of copper wires lead to severe signal attenuation and a sharp rise in power consumption.
In response, the industry widely believes that silicon photonics technology—which replaces electrons with photons for data transmission—is a key solution to address high energy consumption and signal latency.
As a new type of device integrating semiconductor and photonics technologies, silicon photonic chips leverage core advantages of high bandwidth, low power consumption, miniaturization, and full CMOS process compatibility. They are moving from behind the scenes in data centers to the forefront of AI computing clusters, becoming the core solution to break through this bottleneck.
Industry consensus is now clear: 2026 will be the key turning point for large-scale commercial adoption of silicon photonics technology—widely recognized as the first year of silicon photonic chip commercialization.
According to a Nomura Securities research report, shipments of 800 G and 1.6 T optical modules will more than double in 2026, with silicon photonics technology expected to achieve a penetration rate of 50%–70% in this market, becoming the core engine of industry growth. As a core component of optical modules, silicon photonic chips account for as much as 30%–70% of the cost. Their foundry capacity and technological level directly determine the development pace of downstream industries. Estimates indicate that global advanced optical chip capacity will grow more than 80% year-over-year in 2026, yet it will still lag behind market demand by 5%–15%, creating a clear capacity gap that further intensifies competition among major foundry players.
This wave is not only reshaping chip design logic but also igniting a new round of fierce competition in the global wafer foundry sector. This massive market has made foundries realize that whoever masters silicon photonics foundry services will hold the entry ticket to the next generation of high-performance computing and AI chips.
To this end, global foundry giants are all actively entering the field and ramping up investments. An intense battle surrounding silicon photonic chip foundry services has fully begun.
