As an indispensable complement to an integer vortex beam, the fractional vortex beam has
unique physical properties such as radially notched intensity distribution, complex phase …

Diffraction is a phenomenon related to the wave nature of light and arises when a
propagating wave comes across an obstacle. Consequently, the wave can be transformed in …

Perfect vector vortex beams (PVVBs) have attracted considerable interest due to their
peculiar optical features. PVVBs are typically generated through the superposition of perfect …

We derive a mathematical description of a perfect vortex beam as the Fourier transformation
of a Bessel beam. Building on this development, we experimentally generate Bessel–Gauss …

We propose theoretically and verify experimentally a method of combining a q-plate and a
spiral phase plate to generate arbitrary vector vortex beams on a hybrid-order Poincaré …

Perfect vortex beams are the orbital angular momentum (OAM)-carrying beams with fixed
annular intensities, which provide a better source of OAM than traditional Laguerre …

Chirality arises universally across many different fields. Recent advancements in artificial
nanomaterials have demonstrated chiroptical responses that far exceed those found in …

This book deals with theoretical bases of the modern optics division concerned with
coherent light fields with singularities characterized by phase uncertainty. Singular light …

Perfect vortex (PV) beams possessing annular intensity profiles independent of topological
charges promise significant advances in particle manipulation, fiber communication, and …
