Breakthrough in OCS: Mass‑production of Large‑Array MEMS Micromirror Chips for AI Data‑Centers

Sep 24, 2026

As AI large‑model training scales up rapidly, modern computing clusters are expanding toward tens‑of‑thousands‑of‑GPU deployments. Traditional electrical switching networks hit bottlenecks on bandwidth, latency and power consumption. Optical Circuit Switching (OCS) becomes a promising solution for next‑generation data centers, since it reconstructs light paths directly within the optical domain without repeated optical‑electrical conversion.

MEMS micromirror array technology currently holds more than 90 % of the commercial OCS market. Thousands of tiny electrostatic‑driven mirrors on one silicon wafer steer incoming light beams to different output ports. It delivers low optical insertion loss below 3 dB, high reliability and excellent port‑scaling capability, widely adopted by hyperscale players such as Google and Lumentum. Market forecasts expect the global OCS market to grow quickly and exceed USD 2.5 Billion by 2029.

**Key technical specifications of mass‑produced large‑array MEMS micromirror chips**

Domestic supplier Zhixin Sensing has achieved mass‑production for large‑port MEMS micromirror arrays up to 400×400 ports, with die‑level yield above 90 %.
The single chip integrates 416 micromirror units using honeycomb‑style layout, supporting dual‑axis mechanical deflection: ±6.5° for X‑axis and ±5.5° for Y‑axis.
Gold‑coated mirror surfaces deliver over 96 % reflectivity across 1260 nm‑1660 nm telecom wavelength bands, with surface roughness lower than 10 nm. Switching response time is under 10 ms.

For reliability, the chip operates stably from ‑10 °C to 75 °C. Temperature drift stays within 0.01°, and cycle lifetime exceeds 1 billion switching cycles, satisfying continuous long‑run operation inside data‑center facilities. Manufactured on 6‑inch and 8‑inch wafer platforms, these chips target large‑scale AI compute clusters, telecom backbone networks and optical switching hardware.

**Application outlook**

OCS based on MEMS micromirrors solves critical pain‑points for modern AI infrastructure. As demand for domestic‑supply optical components rises, high‑volume MEMS micromirror arrays will play an increasingly important role in data‑center optical interconnection systems.
