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…
3D Heterogeneous Integration of Silicon Nitride and Aluminum Nitride on Sapphire toward Ultra-wideband Photonics Integrated Circuits
Liang Zhang, Yanan Guo, Junxi Wang +2
Extending two-dimensional photonic integrated circuits (PICs) to three-dimensional (3D) configurations promises great potential for scaling up integration, enhancing functionality,…
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…
