“…But this is not compatible with a recently identified natural separation between orbital and spin current (Bekshaev & Soskin 2007;Berry 2009;Bliokh et al 2010). One way to see this is to note that there can be a transverse shift for oblique linear polarizations, i.e.…”

In-plane (lateral) and out-of-plane (transverse) shifts in the direction of arbitrarily polarized electromagnetic waves in a denser medium, reflected totally or partially at an interface with a rarer medium, are calculated exactly, in terms of the deviation of the Poynting vector from radial. The shifts are analogous to the Goos-Hänchen and FedorovImbert shifts for beams. There is a transverse shift even for unreflected dipole radiation if the polarization is not linear. With reflection, there is a transverse shift for linear polarization, provided this is not pure transverse electric or transverse magnetic. The contributions from the geometrical ray, the lateral ray that interferes strongly with it, and the large peak at the Brewster angle (for transverse magnetic polarization), are calculated asymptotically far from the geometrical image. At the critical angle, the lowest order asymptotics is inadequate and a more sophisticated treatment is devised, reproducing the exact shifts accurately.

Spatial distribution of longitudinal field component of circularly polarised optical beam depends on the polarization handedness, which causes a lateral shift of "centre of gravity" of the beam when its polarization toggles. We present generalised theory of this effect, which demonstrates relation of the latter with angular irradiance moments of the beam. The theory is applicable to arbitrary paraxial beams and shows that the lateral shift is the same for the all cross sections of the beam.

“…Moreover, the superposition of positive and negative vortices produce circulating r/ x; y ð Þ transverse components that cancels out. These transverse components of k are responsible for internal energy flows within the transverse plane [30][31][32][33]. The electric field vector of a tilted interfering RCP/LCP beam, having propagation vector k making a small angle α with z-axis in the x-z plane, is given by:…”

Cylindrical vector beams with azimuthal and radial polarization distributions are studied for singularities. It is shown experimentally that these beams have screw dislocation as well as edge dislocation at the same time. The relation between phase and polarization of light beam is the key to understand this fact. We envisage that this has potential application in phase synthesis using polarization engineering. Further, the polarization singularities in these inhomogeneously polarized beams are examined by measuring Stokes parameters across the cross-section of these beams.
