Herein, an attention-grabbing and up-to-date review related to major multiplexing
techniques is presented which includes wavelength division multiplexing (WDM) …

Diffraction is a phenomenon related to the wave nature of light and arises when a
propagating wave comes across an obstacle. Consequently, the wave can be transformed in …

We report an atmospheric multichannel data transmission system with channel separation
by vortex beams of various orders, including half-integer values. For the demultiplexing of …

A technique for simultaneous detection of individual vortex states of the beams propagating
in a randomly inhomogeneous medium is proposed. The developed optical system relies on …

In addition to molecular absorption and scattering from organic and non-organic matter, light
waves propagating through oceanic waters may be affected by optical turbulence, ie …

We present the autofocusing and self-healing properties of aberration laser beams (ALBs) in
a turbulent media. The ALB is generated by a diffractive optical element (DOE) whose phase …

We present a new technique for measuring the squares of the amplitudes and phases of
partial vortex-beams in a complex beam array in real time. The technique is based on …

High-power vortex beams have extensive applications in optical communication, nonlinear
frequency conversion, and laser processing. To overcome a single beam's power limitation …

The possibility of constructing a near-infrared atmospheric optical communication system
based on a pair of media converters of a signal format 100Base-TX/1000BASE-T to format …

We study the propagation of optical vortices in a system which consists of a tandem of a
multi-helical and twisted anisotropic fiber. We show that at certain resonance regimes of the …
