There is a growing interest in structured light, especially orbital angular momentum (OAM)
beams, due to its unique amplitude and phase structure. Multiple orthogonal OAM beams …

Propagation of laser light is distorted in the presence of atmospheric turbulence. This poses
an issue for sensing, free-space optical communications, and transmission of power. The …

Radar imaging based on orbital angular momentum (OAM) beams has become a significant
approach to realize high resolution and multidimensional target detection. The irradiation of …

Free-space optical (FSO) communication links can benefit from recovering both amplitude-
and phase-encoded data (eg, quadrature-amplitude-modulation, QAM) by mixing a local …

Free space optical (FSO) communication has gained widespread attention due to its
advantages, including high confidentiality, high communication capacity, and no limitation of …

Profiting from the fixed vortex-radius, perfect acoustic-vortex (PAV) beams can improve the
efficiency of orbital angular momentum (OAM) communication. While, characteristics of OAM …

Free-space optical (FSO) communications in the mid-infrared (mid-IR) wavelength region
has gained increasing interest due, in part, to the lower atmospheric loss than at lower …

We report on the generation of high-power ultrashort-pulsed optical vortex beams (VBs) with
orbital angular momentum (OAM) of+ 1 in the infrared (IR) and+ 2 in the visible (VIS) spectral …

In this Letter, we demonstrate turbulence mitigation of four mode-division-multiplexing
(MDM) quadrature-phase-shift-keying (QPSK) channels in a pilot-assisted self-coherent free …

Laser based optical applications such as imaging, ranging, and wireless communications
are susceptible to environmental distortions. Inferring the strength of these optical distortions …
