Partially coherent beams with a prescribed phase, state of polarization, and degree of
coherence display many extraordinary propagation properties and are preferred in many …

It has been over 30 years since the concept of optical vortices was first proposed by Coullet
et al. in 1989, and the field of structured beams has grown extremely. In the last two …

The distribution of degree of coherence of a partially coherent vortex beam reveals rich
information about the vortex phase, and it is known that one can determine the topological …

The ability to overcome the negative effects, induced by obstacles and turbulent
atmosphere, is a core challenge of longdistance information transmission, and it is of great …

Due to carrying orbital angular momentum (OAM), vortex beams are also known as OAM
beams. Coherence, as another controllable parameter of the beam, and its joint control with …

Vortex beams with helical phase, carrying phase singularity and orbital angular momentum,
have attract great attention in the past decades due to their wide applications in optical …

For a partially coherent Bessel–Gaussian (PCBG) vortex beam, information regarding the
topological charge (TC) is hidden in the phase of the cross-spectral density (CSD) function …

Ever since vortex beams were proposed, they are known for owning phase singularity and
carrying orbital angular momentum (OAM). In the past decades, coherent optics developed …

In the theory of partial coherence, coherence singularities can occur in the spectral degree
of coherence (SDOC): in case the fields at two different points are completely uncorrelated …

We introduce a new kind of partially coherent vortex (PCV) beam with fractional topological
charge named partially coherent fractional vortex (PCFV) beam and derive the propagation …
