Herein, we have discussed three major methods which have been generally employed for
the generation of optical beams with orbital angular momentum (OAM). These methods …

Polarization singularities are superpositions of orbital angular momentum (OAM) states in
orthogonal circular polarization basis. The intrinsic OAM of light beams arises due to the …

Recent advances in metasurfaces, ie, two-dimensional arrays of engineered nanoscale
inclusions that are assembled onto a surface, have revolutionized the way to control …

Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

Polarization singularities are superpositions of orbital angular momentum (OAM) states in
orthogonal circular polarization basis. The intrinsic OAM of light beams arises due to the …

We propose an approach for creating optical vortex array (OVA) arranged along arbitrary
curvilinear path, based on the coaxial interference of two width-controllable component …

Lens design is of paramount importance in the evolving world of technology, where
compactness and high optical performance are a necessity, ranging from smartphones and …

Enabled by multiple optical traps, holographic optical tweezers can manipulate multiple
particles in parallel flexibly. Spatial light modulators are widely used in holographic optical …

We consider methods for obtaining a multitude of structured laser beams (multiplexing) from
an illuminating beam (both structured and unstructured) with the help of diffractive optical …
