MEMS-based optical switches: a strategic technology for AI data centers

The optical MEMS market is valued at $1 billion in 2025, and growth is estimated at 15% CAGR_25-31. Much of this growth is driven by the rapid adoption of Optical Circuit Switching (OCS) in data centers (DCs) supporting AI workloads.

Although optical MEMS are used across a broad range of applications, including light projection systems for consumer/industrial projectors as well as head-up display modules, they also play a key role in optical communication. First developed in the early 2000s, optical switches were initially deployed in fiber-optic networks. In recent years, however, leading technology companies such as Google, NVIDIA, and AWS have shown growing interest in leveraging optical MEMS within OCS architectures for next-generation data centers.
