We study the directional excitation of optical surface waves controlled by the magnetic field of light. We theoretically predict that a spinning magnetic dipole develops a tunable unidirectional coupling of light to TE-polarized Bloch surface waves (BSWs). Experimentally, we show that the helicity of light projected onto a subwavelength groove milled in the top layer of a 1D photonic crystal (PC) controls the power distribution between two TE-polarized BSWs excited on both sides of the groove…

This study shows that symmetry can be broken over a broad spectral bandwidth by using incident circularly polarized light, on the basis of a spin-orbital angular momentum transfer directly within waveguide bends, and predicts that up to 94% of the incoupled light is directed into a single propagation channel of a gap plasmon waveguide.

It is shown that polarization-controlled optical modes of metamaterials arise where the spatial inversion symmetry is violated, and the emerged spin-split dispersion of spontaneous emission originates from the spin-orbit interaction of light, generating a selection rule based on symmetry restrictions in a spin-optical meetamaterial.
