Geometric phase-space nonseparability triggers giant optical shifts
Kaiqi Zhu, Yonglei Liu, Yao Zhao +8
Nonseparability among multiple degrees of freedom has enabled fundamental advances in structured light and related applications. Here we unveil a previously overlooked form of nons…
Incoherent light delivers skyrmionic topological resilience and transitions
Yonglei Liu, Shiqi Chen, Zhenyu Guo +5
Optical skyrmions has recently unlocked topological quasiparticle textures of light, rising in prominence for next-generation ultra-robust information processing. However, to date,…
Phase-space nonseparability, partial coherence, and optical beam shifts
Yahong Chen, Sergey A. Ponomarenko
As a paraxial wave packet is reflected or refracted from a planar interface separating two material media, it experiences spatial and angular shifts of its center position with res…
Spin-orbit interactions of the twisted random light
Benli Li, Yahong Chen, Weimin Deng +3
The twist phase of random light represents a nontrivial two-point phase, endowing the field with orbital angular momentum. Although the mutual transition of the spin and orbit angu…
