Transverse spin dynamics of light: the generalized spin-momentum locking for structured guided modes

  title={Transverse spin dynamics of light: the generalized spin-momentum locking for structured guided modes},
  author={Peng Shi and Luping Du and Congcong Li and Anatoly V. Zayats and Xiaocong Yuan},
Spin-momentum locking, a manifestation of topological properties that govern the behavior of surface states, was studied intensively in condensed matter physics resulting in the discovery of topological insulators. The photonic spin-momentum locking was introduced for surface plane-waves which intrinsically carry transverse optical spin, leading to many intriguing phenomena and applications in unidirectional waveguiding, metrology and quantum technologies. In addition to spin, optical waves can…

Geometrodynamics of spinning light

The semiclassical evolution of spinning particles has recently been re-examined in condensed matter physics, high-energy physics, and optics, resulting in the prediction of the intrinsic spin Hall

Spin and orbital angular momentum of a class of nonparaxial light beams having a globally defined polarization

It is shown that the momentum density of free electromagnetic field splits into two parts. One has no contribution to the net momentum due to the transversality condition. The other yields all the

Coriolis effect in optics: unified geometric phase and spin-Hall effect.

The Berry phase is shown to be a manifestation of the Coriolis effect in a noninertial reference frame attached to the wave, and the unified geometric phase is verified by the observed polarization-dependent shift (spin-Hall effect) of the waves.

Optical transverse spin coupling through a plasmonic nanoparticle for particle-identification and field-mapping.

It is demonstrated in experiments that Ag and Au nanoparticles yield distinct imaging patterns when scanned over a focused field, because of their different plasmonic responses to the transverse and longitudinal electric fields.

We write the charge-free Maxwell equations in a form analogous to that of the Dirac equation for a free electron. This allows us to apply to light some of the ideas developed for the relativistic
