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…
Reconstructive comb spectroscopy: A single-pixel detection paradigm beyond dual-comb limitations
Dongxu Zhu, Zhuoren Wan, Xiaoshuai Ma +13
Frequency comb spectroscopy has revolutionized broadband molecular fingerprinting with mode-defined resolution. While dual-comb spectroscopy stands as a dominant paradigm for high-…
High-speed hyperspectral 3D ghost imaging LiDAR
Jing Hu, Wending Huang, Tianjian Lv +7
Light detection and ranging (LiDAR) is widely used in autonomous systems and industrial metrology; however, the simultaneous acquisition of three-dimensional (3D) structure and bro…
Broadband terahertz comb with sub-Hz comb linewidth
Min Li, Yu Xia, Yuan Chen +6
Terahertz (THz) frequency combs are increasingly essential for spectroscopy, metrology, and quantum science. However, generating a dense array of evenly spaced ultra-narrow THz com…
Dual-comb correlation spectroscopy reveals laser dynamics
Xiuxiu Zhang, Zhuoren Wan, Yuling Sheng +6
Laser dynamics underpin a broad range of modern photonic technologies and continue to reveal rich nonlinear behaviors. However, existing spectroscopic tools, most notably time-stre…
