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).

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 ...

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 ...

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 ...
