Comb-enabled spectral-domain image transport through perturbation-prone multimode fibers
Maohan Li, Zijian Wang, Bowen Sun +9
Multimode fibers (MMFs) offer a compact platform for imaging, sensing, and information transport, but their practical deployment is hindered by sensitivity to fiber perturbations,…
Free-running single-cavity dual combs with Hz-level relative linewidth
Yuan Chen, Ming Yan, Jia Xu +7
Single-cavity dual-comb lasers provide a compact and efficient source for dual-comb spectroscopy in gas sensing applications; however, achieving sufficient free-running mutual cohe…
Reducing Averaging Time in Dual-comb Spectroscopy via Phase-Patterned Higher-Repetition-Rate Pulses
Wei Long, Xinru Cao, Xiangze Ma +3
Dual-comb spectroscopy (DCS) is a powerful Fourier-transform spectroscopic technique that provides high-speed, high-resolution, and broadband measurements without moving parts. How…
Overcoming the noise-tracking-bandwidth limits in Free-running Dual-Comb Interferometry
Wei Long, Yujia Ji, Xiangze Ma +1
We present a straightforward method to extend the noise-tracking bandwidth for self-correction algorithms in free-running dual-comb interferometry, leveraging coherent-harmonic-enh…
