Optical trapping and manipulation of objects down to the Ångstrom level has revolutionized
research at the smallest scales in all natural sciences. The flexibility of optical trapping …

HoloTile is a patented computer generated holography approach with the aim of reducing
the speckle noise caused by the overlap of the non-trivial physical extent of the point spread …

Helico-conical optical beams, different from higher-order Bessel beams, are generated with
a parallel-aligned nematic liquid crystal spatial light modulator (SLM) by multiplying helical …

Counterpropagating light fields provide a stationary optical potential well for a Brownian
particle. Introducing variability in the relative strengths of the counterpropagating beams …

We transform a TEM 00 laser mode into multiple counterpropagating optical traps to achieve
four-dimensional simultaneous manipulation of multiple particles. Efficient synthesis and …

Of late, generation of different kinds of optical vortex lattices has been gaining much
attention due to various applications. Several methods have been reported for the …

Light intensity is easily quantified by using calibrated detectors that can directly exploit the
energy flux from an incident light. Spatial intensity variations can be imaged using an array …

We investigate the formation of single and multiple optical bottle beams on the optical axis
using a diffractive axicon with amplitude or phase apodization. The proposed approach …

Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

In this paper, we demonstrate the formation of optical vortices (OV) array through in-line
modulation of phase distributions using the approach of concatenation. This approach is …
