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.

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.

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

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.

Angular momentum decomposition of nonparaxial light beams
Optics Express, 2010 The total angular momentum per unit length of a general non-paraxial beam is decomposed into an orbital component associated with the spiral spectrum at the far field and a component concerning the balance between right- and left-handed circular-polarization content of the angular spectrum. Expressions for the linear momentum and energy per unit length

Poincare Invariant Algebra From Instant to Light-Front Quantization [PDF]
, 2001 We present the Poincare algebra interpolating between instant and light-front time quantizations. The angular momentum operators satisfying SU(2) algebra are constructed in an arbitrary interpolation angle and shown to be identical to the ordinary ...
