The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven
by the tremendous developments in the toolkit for the creation, control and detection of what …

Diffraction is a cornerstone of optical physics and has implications for the design of all
optical systems. The paper discusses the so-called'non-diffracting'light field, commonly …

Abstract “Non‐diffracting” beams do not spread as they propagate. This property is useful in
many areas. Here, the theory, generation, properties, and applications of various “non …

We study theoretically and experimentally the spatial intensity distribution of the zero-order
Bessel beam formed by the axicon which possess a rounded tip. Such a tip generates a …

We present for the first time a comparison under similar circumstances between Laguerre–
Gauss beams (LGBs) and Bessel beams (BB), and show that the former can be a better …

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 …

We present results on the second-harmonic generation using nondiffracting speckle fields in
the fundamental frequency to pump a nonlinear medium to obtain the sum-frequency …

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 …

Ideal full Poincaré (FP) beams contain all possible polarization states on the surface of the
Poincaré sphere and are readily created by linear optical techniques and, more recently, by …

We report a simple method for generating microaxicons at the extremity of commercial
optical fibers. The proposed solution, based on a polishing technique, can readily produce …
