Multi-Soliton Microcombs Enable Ultrafast Nanometric-Precision Ranging and Photon-Level Detection.

ABSTRACT: Optical microcombs offer unprecedented capabilities in precision ranging due to their compact footprint, broad spectral bandwidth, and high repetition rates. However, practical deployment is limited by a fundamental compromise: single-soliton states exhibit high coherence but low power conversion efficiency, whereas chaotic microcombs achieve higher efficiency at the expense of significant phase noise. Here, we overcome both limitations by implementing multi-soliton microcombs in dual-comb system. Multi-soliton states provide higher efficiency and easier accessibility than single-soliton states, while maintaining high coherence essential for nanometric precision compared to chaotic states. Experimental results indicate that utilizing three solitons in both combs, the measurement uncertaint
