We present a proof of concept for a vector beam polarization state spectrum analyzer based on the combination of a polarization diffraction grating (PDG) and an encoded harmonic q-plate grating (QPG).

Recently, researchers at Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences generated novel multicolor concentric annular ultrafast vector beams (MUCAU-VB) based ...

Vector-vortex beams, having both phase and polarization singularities, are of great interest for a variety of applications. Generally, such beams are produced through systematic control of phase and ...

Typically, light emitted from standard lasers has a controllable degree of freedom (DoF) which may be polarisation or beam shape. By suitably manipulating a laser with the introduction of specialised ...
