Summary

Two startups, Lumotive and Neurophos, are leveraging metamaterials to enhance data center bandwidth and accelerate artificial intelligence processing. Lumotive, which debuted a new microchip on March 19, has developed metamaterials with electronically programmable liquid crystal elements to precisely steer, lens, shape, and split light beams. This technology aims to improve optical circuit switches, offering a no-moving-parts solution that can scale up to 10,000 by 10,000 ports, with initial products expected by late 2026. Neurophos is developing metamaterial-based optical modulators, the optical equivalent of transistors, that are 1/10,000th the size of current designs. These chips, built using standard CMOS processes, are projected to offer 50 times greater compute density and energy efficiency than Nvidia's Blackwell-generation GPUs, with proof-of-concept chips for hyperscalers this year and systems targeting early 2028.

Key takeaway

For CTOs and infrastructure architects evaluating next-generation data center and AI compute solutions, Lumotive's and Neurophos's metamaterial-based technologies present a compelling alternative to conventional electronic and existing optical systems. Your teams should monitor the performance and scalability of these emerging optical switches and AI processors, especially Lumotive's planned 2026 launch and Neurophos's 2028 production target, to assess their potential for significant improvements in energy efficiency and compute density.
