Perfect optical coherence lattices
Liang Chunhao, Liu Xin, Xu Zhiheng +4
We advance and experimentally implement a protocol to generate perfect optical coherence lattices (OCL) that are not modulated by an envelope field. Structuring the amplitude and p…

Anomalous multi-ramp fractional vortex beams with arbitrary topological charge jumps
Jun Zeng, Zhiheng Xu, Chengliang Zhao +2
Traditional fractional vortex beams are well-known "jump" beams: that is, their net topological charge jumps by unity as the effective topological charge of the source passes a hal…
