Robust Packaged Fiber-Microcavity Device with over One Billion Q-factor
Fangxing Zhang, Shengnan HuangFu, Jialve Sun +3
Whispering gallery mode (WGM) microcavities can confine photons within a microscale volume for long periods of time, strongly enhancing light-matter interactions, and making it a c…
Phonon-induced anomalous gauge potential for photonic isolation in frequency space
Jianfan Yang, Luqi Yuan, Tian Qin +6
Photonic gauge potentials are crucial for manipulating charge-neutral photons like their counterpart electrons in the electromagnetic field, allowing analogous Aharonov-Bohm effect…
Synthetic parity-time symmetry breaking in a single microcavity
Fangxing Zhang, Yaming Feng, Li Ge +1
Non-Hermitian systems based on parity-time (PT) symmetry reveal rich physics beyond the Hermitian regime. So far, realizations of PT-symmetric systems have been limited to the spat…
Slow and fast light enhanced light drag in a moving microcavity
Tian Qin, Jianfan Yang, Fangxing Zhang +7
Fizeau experiment, inspiring Einstein's special theory of relativity, reveals a small dragging effect of light inside a moving medium. Dispersion can enhance such light drag accord…
Passive thermal fine-tuning of whispering gallery mode for nonlinear optics in a microcavity
Yaming Feng, Yuanlin Zheng, Fangxing Zhang +3
Whispering gallery mode (WGM) microcavities strongly enhance nonlinear optical processes like optical frequency comb, Raman scattering and optomechanics, which nowadays enable cutt…
