Magnified photonic spin-Hall effect with curved hyperbolic metamaterials.

Photonic spin-Hall effect is significantly magnified in a curved hyperbolic metamaterial (hyperlens) with hyperbolic dispersion. We theoretically and numerically analyze the magnification of the photonic spin-Hall effect from a single dipole emitter. Through studying the dispersion of the curved hyperbolic metamaterial, a maximum half angular separation of 45.0° between the right-handed circular and left-handed circular polarization channels can be obtained. Moreover, the curved hyperbolic metamaterial can provide a complete separation of the spin dependent radiation channels. Such a magnified photonic spin-Hall effect may find potential applications in quantum information processing, directional switching, and polarization sorting. [ABSTRACT FROM AUTHOR]
