Herein, we have discussed three major methods which have been generally employed for
the generation of optical beams with orbital angular momentum (OAM). These methods …

Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

Measuring orbital angular momentum (OAM) states of vortex beams is of great importance in
diverse applications employing OAM-carrying vortex beams. We present a simple and …

We report waveguide-addressed plasmonic–photonic resonators that generate beams of
controlled orbital angular momentum and spin angular momentum content upon driving …

An integrated approach to produce photonic orbital angular momentum (OAM) superposition
states with arbitrary OAM spectrum has been demonstrated. Superposition states between …

Due to the nature of infinite dimensionality, the orbital angular momentum (OAM) has been
considered as a new degree of freedom of light and widely expanded the scopes of …

Smith–Purcell radiation (SPR) is the electromagnetic wave generated by free electrons
passing above a diffraction grating, and it has played an important role in free-electron light …

摘要近些年来, 涡旋光束特有的相位结构和携带轨道角动量(OAM) 特性, 使其在光通信, 光操纵,
成像, 传感到量子信息等领域具有广泛的应用前景. 但这些应用都必须依赖于高质量涡旋光束的 …

As a fundamental tool for light-matter interactions, plasmonic vortex (PV) is extremely useful
due to the unique near field property. However, it is a pity that, up to now, the orbital angular …

Using a numerical simulation, we investigate the possibility of synthesising vortex laser
beams with a variable orbital angular momentum by a hexagonal array of fibre lasers under …
