Abnormal motions of optical vortex-antivortex-coupled wavepackets in the parabolic potential
Haolin Lin, Junhui Jia, Chunhao Liang +4
The (quasi)particles or structured wavepackets in parabolic potential exhibit well-known harmonic oscillations, typically described by the Lissajous equations. However, such conven…

Photonic Spin-Orbit Coupling Induced by Deep-Subwavelength Structured Light
Xin Zhang, Guohua Liu, Yanwen Hu +6
We demonstrate both theoretically and experimentally beam-dependent photonic spin-orbit coupling in a two-wave mixing process described by an equivalent of the Pauli equation in qu…

Optical Superoscillatory Poisson-Arago Spots
Yanwen Hu, Shenhe Fu, Zhigui Deng +5
Optical diffraction limit has been a long-term scientific issue since Ernst Abbe first introduced the concept in 1873. It is a constraint on the smallest light spot that can be ach…
