Multi‐channel modulation of Jones matrix facilitates encoding a variety of different functions
in metasurfaces. However, multiple channels are usually accompanied by a high system …

Optical image/data encryption techniques are mostly based on the manipulation of spatial
distributions of light's amplitude, phase, and polarization. Information encoding with phase …

Optical cryptosystems mostly use spatial distributions of amplitude, phase, and polarization
of light to encrypt two-dimensional data/image. In this letter, we demonstrate the use of light …

Vector-vortex (VV) beams are of significant interest for various applications. There have
been substantial efforts toward developing a fast and efficient method for the …

Structured light carrying optical vortices have gained significant attention in information
security as they offer high-dimensional orthogonal states for encoding. These states are …

Metasurface‐based holography provides tremendous advances in multi‐dimensional
detection, super‐resolution imaging, and cryptography applications. Current mainstream …

We propose an asymmetric image encryption scheme that employs chaotic phase masks
and vectorial light field. Vector light fields have non-uniform state of polarization across the …

Precise control of amplitude and wavefront of optical fields are prerequisites for many
applications, especially in singular optics. This has led to the increasing efforts for …

Phase and polarization singularities are two important quantities for cylindrical vector vortex
beams (CVVBs), and the efficient and accurate detection of both singularities simultaneously …

Vector light fields have spatially non-uniform polarization across the transverse plane. In this
study, a color image encryption scheme has been proposed in which the data is encoded …
