Integrated vortex soliton microcombs
Yanwu Liu, Chenghao Lao, Min Wang +9
The frequency and orbital angular momentum (OAM) are independent physical properties of light that both offer unbounded degrees of freedom. However, creating, processing, and detec…
Micropascal-sensitivity ultrasound sensors based on optical microcavities
Hao Yang, Xuening Cao, Zhi-Gang Hu +6
Whispering gallery mode (WGM) microcavities have been widely used for high-sensitivity ultrasound detection, due to their optical and mechanical resonances enhanced sensitivity. Th…
Fully reconfigurable optomechanical add-drop filters
Yuechen Lei, Zhi-Gang Hu, Min Wang +4
Fully reconfigurable add-drop filters (ADFs) have important applications in optical communication and information processing. Here we demonstrate a broadly tunable add-drop filter…
High sensitivity air-coupled MHz frequency ultrasound detection using on-chip microcavities
Hao Yang, Zhi-Gang Hu, Yuechen Lei +7
Owing to their dual-resonance enhanced sensitivity, cavity optomechanical systems provide an ideal platform for ultrasound sensing. In this work, we realize high sensitivity air-co…
