Silicon modulator uses 'slow light' for efficient data signal conversion

Researchers built a silicon modulator with nanoscale holes that slow light to improve signal conversion efficiency. The design targets fiber-optic links in AI data centers, where copper wiring works only over distances under 1 m.
