Polarization coverage and self-healing characteristics of Poincaré-Bessel beam
Subith Kumar, Anupam Pal, Arash Shiri +2
As a vector version of scalar Bessel beams, Poincaré-Bessel beams (PBBs) have attracted a great deal of attention due to the presence of polarization singularities and their nondif…
Deterministic vortices evolving from partially coherent fields
Wenrui Miao, Yongtao Zhang, Greg Gbur
It has long been assumed that there is an intrinsic conflict between optical vortices and partial coherence, in that deterministic phase vortices do not appear in partially coheren…
Simple experimental realization of optical Hilbert Hotel using scalar and vector fractional vortex beams
Subith Kumar, Anirban Ghosh, Chahat Kaushik +4
Historically, infinity was long considered a vague concept - boundless, endless, larger than the largest - without any quantifiable mathematical foundation. This view changed in th…
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…
Correlation-induced orbital angular momentum changes
Yongtao Zhang, Olga Korotkova, Yangjian Cai +1
We demonstrate that the orbital angular momentum flux density of a paraxial light beam can change on propagation in free space. These changes are entirely due to the spatial cohere…
Fractional vortex Hilbert's Hotel
Greg Gbur
We demonstrate how the unusual mathematics of transfinite numbers, in particular a nearly perfect realization of Hilbert's famous hotel paradox, manifests in the propagation of lig…
