Spin-Orbit Interaction of Lightby Tailoring Spatial PolarizationStates
2016
We propose that as an alternative to using metamaterials for polarization
dependent manipulation of light, spatial gradient of geometric
phase can be generated by spatially tailoring the incident
beam and only using materials with homogeneous anisotropy. In
this thesis we start by exploring the geometric phase gradient of
light when it passes through inhomogeneous anisotropic materials
and observe the SOI effects resulting from this. Next, we use polarization
tailored cylindrically symmetric beams incident on homogeneous
isotropic/anisotropic media to observe rotational spin-hall effect
of light. Finally, we use beams with cylindrical symmetry broken
polarizations (generated with SLM) to observe angular shift in trajectory
of the beam (and hence shift in beam centroid on the screen) for
LCP/RCP projections.
