Microcomb-based phase-sensitive interferometry is demonstrated over a broad bandwidth using power-efficient solitons. This work highlights the possibilities of spatial multi-sensing using chip-scale frequency combs enabled by wafer-scale manufacturing with a high yield. © Optica Publishing Group 2024
