Acoustic orbital angular momentum Hall effect and realization using a metasurface
Physical Review Research, 2021 Vortex beams with a twisted wavefront possess both intrinsic and extrinsic orbital angular momenta. Their coupling (viz. orbital-orbital coupling) leads to an orbital angular momentum Hall effect previously found in light, providing applications in light

Efficient Sorting of Orbital Angular Momentum States of Light
Physical Review Letters, 2010 We present a method to efficiently sort orbital angular momentum (OAM) states of light using two static optical elements. The optical elements perform a Cartesian to log-polar coordinate transformation, converting the helically phased light beam corresponding to OAM states into a beam with a transverse phase gradient.

Carrying Data on the Orbital Angular Momentum of Light [PDF]
IEEE Communications Magazine, 2018 The use of fiber optic cable in support of bandwidth expansion has become de rigeur. Not only does optical fiber offer tremendous bandwidth, it is also low in attenuation, small in cross section, inexpensive, and impervious to electromagnetic interference, and there are significant economies of scale on components developed for the myriad of optical ...

Partonic angular momentum in the nucleon's chiral periphery
Physics Letters B, 2019 We study the nucleon's partonic angular momentum (AM) content at peripheral transverse distances b=O(Mπ−1), where the structure is governed by chiral dynamics.

Amplification and generation of ultra-intense twisted laser pulses via stimulated Raman scattering
Nature Communications, 2016 High intensity light with a non-zero orbital angular momentum could aid the development of laser-wakefield particle accelerators. Here, the authors theoretically show that stimulated Raman backscattering in plasmas can generate and amplify orbital ...

Detection of a Spinning Object Using Light’s Orbital Angular Momentum [PDF]
Science, 2013 Doppler Effect with a Twist The Doppler shift is a familiar and well-understood effect in acoustics. Radar guns use the same effect to determine the speed of moving vehicles. Applied to a rotating object side-on, however, a linear Doppler effect would register no movement. Using twisted light, whereby photons are imprinted with a

Propagable Optical Vortices with Natural Noninteger Orbital Angular Momentum in Free Space
Advanced Photonics Research, 2023 Light beams with optical vortices can propagate in free space only with integer orbital angular momentum. Herein, this scientific consensus theoretically and experimentally is upheaved by proposing light beams carrying natural noninteger orbital angular ...

Transfer of Orbital Angular Momentum of Light Using Autler-Townes Splitting
Photonics, 2022 We propose a scheme to exchange optical vortices beyond electromagnetically induced transparency (EIT) but based on four-wave mixing (FWM) in a five-level atomic system consisting of two Λ subsystems linked via a weak driving field. When the laser fields
