Optical twist has always been a hot spot in optics since it was discovered in 1993. Twisted
beams can be generated by introducing the twist phase into partially coherent beams, or by …

Optical twists are the rotation of light structures along the beam axis, which can be caused
by the quadratic twist phase of a partially coherent field. Here, we introduce a new class of …

Since the celebrated twist phase was proposed by Simon and Mukunda, despite the
tremendous progress made in theory over the past decades, developing a simple and …

Featured Application The results provide a useful guideline for manipulation of novel vector
structure beams by using twist phases and customized correlation functions, and promote …

We present coherent and partially coherent beams that exhibit transverse pattern expansion
and rotation upon free propagation. Coherent twisting beams may be generated by a …

Twist phase is a nontrivial second-order phase that only exists in a partially coherent field,
providing a new degree of freedom for manipulating statistical properties of random light …

We present both numerical and experimental results to study the diffraction of twisted light
beams based on orbital angular momentum (OAM) eigenmode decomposition, where the …

While photons travel in a straight line at constant velocity in free space, the intensity profile of
structured light may be tailored for acceleration in any degree of freedom. Here we propose …

Light beams with helical phase profile correspond to photons having orbital angular
momentum (OAM). A Laguerre-Gaussian (LG) beam is an example where its helical phase …

We introduce a radially polarized partially coherent twisted beam based on the unified
theory of coherence and polarization. We also derive expressions of this beam propagating …
