The existence of the edge states at the interface between two media with different
topological properties is protected by symmetry, which makes such states robust against …

Optical hollow beams are suitable for materials processing, optical micromanipulation,
microscopy, and optical lithography. However, conventional optical hollow beams are …

We propose a simple method for the generation of multi-contour plane curves based on
vortex beam illumination of an optical element calculated using the Whittaker integral and …

We introduce an exactly integrable nonlinear model describing the dynamics of spinor
solitons in space-dependent matrix gauge potentials of rather general types. The model is …

We put forward a new optical system, which is composed of an existing axicon doublet and a
newly proposed amplitude filter. The axicon doublet consists of a positive axicon and a …

Metasurfaces with linear phase gradients can redirect light beams. Controlling both phase
and amplitude of a metasurface is proposed to extend Snell's law to the realm of complex …

This paper presents a scheme exploiting a uniform circular frequency diverse array (UC-
FDA) of optical beamlets to realize non-diffracting beams with unprecedented switching …

A functional metasurface of both transparent medium slices and multiple deflection prisms is
proposed, where phase retardations for generating non-diffracting vortex lattices are …

We show that it is possible to generate transversely random, diffraction-free/longitudinally
invariant vector optical fields. The randomness in transverse polarization distribution …

We propose a method for generating three-dimensional light fields with given intensity and
phase distributions using purely phase transmission functions. The method is based on a …
