Self-healing of light refers to the ability of a light field to recover its structure after being
damaged by a partial obstruction placed in its propagation path. Here, we will give a …

Optical communication is an integral part of the modern economy, having all but replaced
electronic communication systems. Future growth in bandwidth appears to be on the horizon …

We investigate the atmospheric turbulence effects on orbital angular momentum (OAM)
spectra of different kinds of vortex beams, including Laguerre–Gaussian (LG) beams and …

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 …

A new approach for generating long‐distance self‐healing Bessel beams, which is based on
a ring‐shaped (annular) lens and a spherical lens in 4f‐configuration, is reported. With this …

Optical vortex beam with fractional orbital angular momentum (OAM) has great potential to
increase the capacity of optical communication and information processing in classical and …

We present an alternative orbital angular momentum (OAM) solution for free-space optical
communications in the form of shape-invariant Bessel beams. We use a generalized …

It is understood from the conical wave picture that Bessel beams may self-heal after certain
opaque obstructions, but the extrapolation to transparent phase screens is not self-evident …

We design and demonstrate what we called shape-preserving “optical pin beams”(OPBs)
that possess stable wavefronts against diffraction and ambient turbulence during free-space …

We report experiments on propagation of scalar and vector optical beams through random
phase screens mimicking turbulence and show that the intensity profile of the beam …
