Optical orbital angular momentum [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017 We present a brief introduction to the orbital angular momentum of light, the subject of our theme issue and, in particular, to the developments in the 13 years following the founding paper by Allen et al. (Allen et al. 1992 Phys. Rev. A 45, 8185 (doi:10.

Spin-constrained orbital-angular-momentum control in high-harmonic generation
Physical Review Research, 2019 The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscopic polarizations of the driving field.

Gravitational waves with orbital angular momentum [PDF]
European Physical Journal C: Particles and Fields, 2020 Compact orbiting binaries like the black hole binary system observed in GW150914 carry large amount of orbital angular momentum. The post-ringdown compact object formed after merger of such a binary configuration has only spin angular momentum, and this ...

Metasurface orbital angular momentum holography [PDF]
Nature Communications, 2019 Conventional hologram designs lack orbital angular momentum selectivity. Here, the authors design metasurface holograms consisting of GaN nanopillars with discrete spatial frequency distributions allowing the reconstruction of distinctive orbital angular

Super-resolution orbital angular momentum holography
Nature Communications, 2023 The resolution of orbital angular momentum holography is limited by a fundamental sampling criterion. Here, the authors break the resolution barrier by temporal multiplexing of binary holograms and enhance the resolution and capacity by several times.

Spin angular momentum modulation via spin–orbit interaction in fractional orbital angular momentum beams [PDF]
NanophotonicsLight exhibits both spin and orbital angular momentum (SAM and OAM). These two forms of angular momentum remain independent in paraxial fields, but become coupled in confined fields through spin–orbit interactions (SOI).

Customizing Multicolored Orbital Angular Momentum Combs. [PDF]
Nano LettCurrent orbital angular momentum (OAM) combs generating technology is hindered by bulky optical systems, limited control, and lack of multicolored information, impeding system integration and practical applications. We present a metasurface approach to realizing multicolored OAM comb engineering along the light propagation direction.

Visualizing a single wavefront dislocation induced by orbital angular momentum in graphene [PDF]
Nature CommunicationsPhase singularities are phase-indeterminate points where wave amplitudes are zero, which manifest as phase vertices or wavefront dislocations. In the realm of optical and electron beams, the phase singularity has been extensively explored, demonstrating ...
