Orbital angular momentum states of light
2020This book provides an in-depth introduction to modelling of long-range propagation of orbital angular momentum modes as well as more general structured light beams through atmospheric turbulence. It is a stand-alone reference material and is well suited to graduate students and researchers in optics and photonics.

Intrinsic angular momentum of light
American Journal of Physics, 1979A familiar theorem involving a balance between net torque and rate of change of angular momentum in the electromagnetic field is rederived. This version of the theorem includes the intrinsic torques exerted by the fields on the polarized medium. It is seen that these terms lead naturally to the expression for the intrinsic angular momentum carried by a

Dividing orbital angular momentum of light
2016 15th International Conference on Optical Communications and Networks (ICOCN), 2016For the first time, we put forward an orbital angular momentum (OAM) divider based on coordinate transformation. The device can convert the OAM light into multiple diffracted light. The OAM of zeroth-order diffracted light is the product of the input OAM and the scaling parameter. We also extend the scheme to realize equal N-dividing of OAM.

Angular momentum of gaussian light beams
Bulletin of the Russian Academy of Sciences: Physics, 2016Analysis of the orbital angular momentum of paraxial light beams shows that a key role in the formation of this quantity is played by phase relations between longitudinal and transverse radiation fields. When a light beam is circularly polarized or has a helical wave front, the azimuthal component of the Poynting vector and the density of orbital ...

Nature, 1931
THE work of Compton on X-ray scattering led to the general acceptance of the idea that the scattering of radiation by a material particle is a unitary process in which energy and linear momentum are conserved. A molecule is, however, a much more complicated structure than an electron, and the conservation principles by themselves would give us an ...

Subwavelength Focusing of Light with Orbital Angular Momentum
Nano Letters, 2014The spatial structure of light with Orbital Angular Momentum, or "twisted light", closely resembles the shape of atomic wave functions. It could therefore make symmetry-forbidden transitions possible in quantum dots, or "artificial atoms". However, the vanishing intensity in the center of an OAM beam usually makes this effect weak.

Arbitrary spin-to–orbital angular momentum conversion of light
Science, 2017From spins to spirals The polarization state of light can be used in imaging applications and optical communications. Light can also be structured into vortices that carry optical angular momentum, which can be used for micromanipulation and enhancing the capacity of optical communication channels. Devlin et al.

Recent developments in the angular momentum of light present fresh challenges to long established concepts and pave the way for new and wide-ranging applications. The scope for structured light such as optical vortices, in particular, now extends from microfluidics to quantum information.
