Owing to their unique properties, optical fields with complex spatial distribution in the cross section have attracted great attention. These complex optical ve

Generation of optical fields with complex spatial distribution in the cross section is of great interest in application areas where exotic optical fields are de

Vectorial optical fields are a type of structured optical fields with inhomogeneous polarization distribution. They are referred to be inhomogenously polarized

Structured singular light is an ubiquitous phenomenon. It is not only created when light refracts at a water surface but can also be found in the blue daytime s

It is well known that an optical field consists of phase, amplitude, and the state of polarization (SOP). Spatially customized optical field within the cross se
