Cylindrical vector beams and vortex beams, two types of typical singular optical beams
characterized by axially symmetric polarization and helical phase front, possess the unique …

Despite a plethora of applications ranging from quantum memories to high-resolution
lithography, the current technologies to generate vector vortex beams (VVBs) suffer from …

Vector modes are spatial modes that have spatially inhomogeneous states of polarization,
such as, radial and azimuthal polarization. In this work, the spatially inhomogeneous states …

In this work, it is experimentally demonstrated that the nonseparability of vector beams (eg,
radial and azimuthal polarization) can be used to encode information for optical …

Polarization holography is a newly researched field, that has gained traction with the
development of tensor theory. It primarily focuses on the interaction between polarization …
