Observation of Anomalous Orbital Angular Momentum Conservation in Parametric Nonlinearity
Hai-Jun Wu, Bing-Shi Yu, Jia-Qi Jiang +5
Orbital angular momentum (OAM) conservation plays an important role in shaping and controlling structured light with nonlinear optics. The OAM of a beam originating from three-wave…
Topological Transformation and Free-Space Transport of Photonic Hopfions
Yijie Shen, Bingshi Yu, Haijun Wu +3
Structured light fields embody strong spatial variations of polarisation, phase and amplitude. Understanding, characterization and exploitation of such fields can be achieved throu…
Highly sensitive measurement of a megahertz rf electric field with a Rydberg-atom sensor
Bang Liu, Li-Hua Zhang, Zong-Kai Liu +6
Rydberg atoms have great potential in electric field measurement and have an advantage with a large frequency bandwidth from the kHz to the THz scale. However, the sensitivity for…
Directly determining orbital angular momentum of ultrashort Laguerre-Gauss pulses via autocorrelation measurement
Bing-Shi Yu, Chun-Yu Li, Yuanjie Yang +2
Autocorrelation measurement based on second-harmonic generation (SHG), the best-known technique for measuring the temporal duration of ultrashort pulses, could date back to the bir…
Parametric amplification of orbital angular momentum beams based on light-acoustic interaction
Wei Gao, Chunyuan Mu, Hongwei Li +2
A high fidelity amplification of beams carrying orbital angular momentum (OAM) is very crucial for OAM multiplexing and other OAM-based applications. Here, we report the first stud…
Observation of reversible orbital angular momentum transfer based on photon-phonon coupling
Zhihan Zhu, Wei Gao, Chunyuan Mu +1
Orbital angular momentum (OAM) has gained great interest due to its most attractive feature of high dimensionality, and several ground-breaking demonstrations in communication base…
