Torque of guided light on an atom near an optical nanofiber [PDF]
, 2019 We calculate analytically and numerically the axial orbital and spin torques of guided light on a two-level atom near an optical nanofiber. We show that the generation of these torques is governed by the angular momentum conservation law in the Minkowski

Surface angular momentum of light beams
Optics Express, 2014 Traditionally, the angular momentum of light is calculated for "bullet-like" electromagnetic wave packets, although in actual optical experiments "pencil-like" beams of light are more commonly used. The fact that a wave packet is bounded transversely and longitudinally while a beam has, in principle, an infinite extent along the direction of ...

Fourier relationship between angular position and optical orbital angular momentum [PDF]
, 2006 We demonstrate the Fourier relationship between angular position and angular momentum for a light mode. In particular we measure the distribution of orbital angular momentum states of light that has passed through an aperture and verify that the orbital ...

Optomechanical detection of light with orbital angular momentum
Optics Express, 2020 We present the design of an optomechanical device that allows sensitive transduction of the orbital angular momentum of light. An optically induced twist imparted on the device is detected using a photonic crystal cavity optomechanical system. This device allows the measurement of the orbital angular momentum of light when photons are absorbed by the ...

Plasmonic Spiral Nanostructure for Analyzing the Angular Momentum of Light
IEEE Photonics Journal, 2017 A compound plasmonic light analyzer with an elliptical Archimedean spiral nanostructure is proposed analytically and analyzed numerically. The elliptical Archimedean spiral is analogous to an ellipse but has varying semimajor axes.

Spin-orbit interaction of light induced by transverse spin angular momentum engineering [PDF]
, 2017 We report the first demonstration of a direct interaction between the extraordinary transverse spin angular momentum in evanescent waves and the intrinsic orbital angular momentum in optical vortex beams.

Orbital angular momentum 25 years on [invited] [PDF]
, 2017 Twenty-five years ago Allen, Beijersbergen, Spreeuw, and Woerdman published their seminal paper establishing that light beams with helical phase-fronts carried an orbital angular momentum. Previously orbital angular momentum had been associated only with

Comment on half-integer quantum numbers for the total angular momentum of photons in light beams with finite lateral extensions [PDF]
, 2017 Recently the spectacular result was derived quantum mechanically that the total angular momentum of photons in light beams with finite lateral extensions can have half-integer quantum numbers.

Orbital angular momentum of light for communications [PDF]
Applied Physics Reviews, 2021 Structured light, especially beams carrying orbital angular momentum (OAM), has gained much interest due to its unique amplitude and phase structures. In terms of communication systems, multiple orthogonal OAM beams can be potentially utilized for increasing link capacity in different scenarios.
