Photonic timing-engineered solitons for dual-microcomb metrology
Zihao Wang, Guoliang Li, Changrui Liu +5
Dissipative microcavity solitons offer a route to integrate comb-based metrology systems on photonic chips. However, integrated solitons generally lack agile control of comb parame…
Overcoming sensitivity-bandwidth trade-off in mid-infrared spectroscopy by a microresonator-anchored swept laser
Zhaoyu Cai, Zihao Wang, Yulei Ding +11
Optical frequency combs have revolutionized high-precision spectroscopy, yet an intrinsic trade-off between spectroscopic signal-to-noise ratio (sSNR) and measurement bandwidth ($B…
High-Q AlN microresonators for nonlinear near-infrared and near-visible photonics
Yulei Ding, Yuming Huang, Zhongdong Yin +9
High Q-factors of microresonators are crucial for nonlinear integrated photonics, as many nonlinear dynamics have quadratic or even cubic dependence on Q-factors. The unique materi…
Self-injection locking dynamics with Raman actions in AlN microresonators
Yulei Ding, Yifei Wang, Shunyu Yao +5
Self-injection locking (SIL) of semiconductor lasers to on-chip microcavities enables significant laser noise purification and diverse nonlinear optical actions. Realizing nonlinea…
Nanometric dual-comb ranging using photon-level microcavity solitons
Zihao Wang, Yifei Wang, Baoqi Shi +4
Absolute distance measurement with low return power, fast measurement speed, high precision, and immunity to intensity fluctuations is highly demanded in nanotechnology. However, a…
A microcomb-empowered Fourier domain mode-locked LiDAR
Zhaoyu Cai, Zihao Wang, Ziqi Wei +5
Light detection and ranging (LiDAR) has emerged as an indispensable tool in autonomous technology. Among its various techniques, frequency modulated continuous wave (FMCW) LiDAR st…
