# Silicon photonics becomes a flashpoint in US-China chip policy

*2026-08-12 · Source: [Tom's Hardware](https://www.tomshardware.com/tech-industry/photonics/how-optical-interconnects-and-silicon-photonics-emerged-as-ais-next-hot-commodity-looming-us-china-summit-puts-photonics-into-the-crosshairs)*

Optical interconnects and silicon photonics have emerged as a critical, fast-growing component in AI data centers, used to move data between GPU clusters at high speed. Ahead of a US-China summit, the US reportedly wants to exclude Chinese-made optical transceivers from future AI data centers, but China currently dominates the photonics supply chain.

**Why it matters:** This extends the chip export-control fight beyond GPUs into the optical networking gear that ties AI clusters together, a component few outside hardware circles were tracking. Given China's current lead in transceiver manufacturing, an effective ban could bottleneck US data-center buildouts even as demand accelerates.

**Topics:** chips, policy, infrastructure
