BACKGROUND Optical vortices provide one of the promising solutions for enhancing the
capacity of data multiplexing to meet an unprecedented growth in big data and internet traffic …

Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within
ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex …

Optical wave packets that are localized in space and time, but nevertheless overcome
diffraction and travel rigidly in free space, are a long sought-after field structure with …

The orbital angular momentum (OAM) of light provides a new degree of freedom for carrying
information. The stable propagation and generation of OAM modes are necessary for the …

We present a method to efficiently multiply or divide the orbital angular momentum (OAM) of
light beams using a sequence of two optical elements. The key element is represented by an …

This paper presents an efficient method to generate high-order Bessel–Gauss beams
carrying orbital angular momentum (OAM) by using a thin and compact optical element such …

Propagation of a continuous spectrum of orbital angular momentum (OAM) states through a
realistic and controlled 3-dimensional turbulent condition has not been studied to date to the …

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 …

This paper presents a novel method for optical probing by generating optical fields with
characteristics of wavelets. The optical wavelets form a basis of rotated asymmetric beams …

A novel optical device is designed and fabricated in order to overcome the limits of the
traditional sorter based on log-pol optical transformation for the demultiplexing of optical …
