Researchers unlock phase control in microring modulators, enabling record-breaking coherent data transmission over 1 Tb/s with just 10.4 fJ/bit energy. Their silicon I/Q modulator achieves >5 Tb/s/mm shoreline bandwidth density. Scalable via WDM, the tech supports 7–20 Tbps/fiber—paving the way for ultra-compact, energy-efficient links in future AI/ML data centers. This breakthrough could redefine interconnects for high-performance, disaggregated computing at scale.
