Abstract

We report the concept of a coherently-parallel fiber-optic distributed-acoustic-sensing, based on integrated dual-soliton-microcombs. It enables linear superposition of acoustic responses scaling with the comb-line number. Leveraging 10-line soliton pairs, a world-class detection limit 560 fε/√Hz@1kHz is achieved.
