Abstract We investigate the photonic spin Hall effect (PSHE) in a symmetrical hyperbolic metamaterial (HMM) waveguide, which is constructed as an HMM/metal/HMM sandwich structure. We consider both type {\uppercase\expandafter{\romannumeral 1}} and type {\uppercase\expandafter{\romannumeral 2}} HMM in the study. We confirm that the structure of alternating sub-wavelength of plasma and dielectric or the structure of embedding plasma into a host dielectric matrix can display effective dielectric, effective metal, type {\uppercase\expandafter{\romannumeral 1}} and {\uppercase\expandafter{\romannumeral 2}} HMM under different wavelength ranges and different plasma fill fraction. This enable us to simultaneously realize type {\uppercase\expandafter{\romannumeral 1}} and type {\uppercase\expandafter{\romannumeral 2}} HMM. We show that the reflectivity ration $\vert r_{s}/r_{p} \vert$, directly related to transverse shifts generated by PSHE, greatly depends on the type and the thickness of HMM. Moreover, we find that the horizontal PSHE shifts are enhanced several times, especially in type {\uppercase\expandafter{\romannumeral 1}} structure; while the vertical PSHE shifts are significantly suppressed in both type {\uppercase\expandafter{\romannumeral 1}} and {\uppercase\expandafter{\romannumeral 2}} structure. By making the effect of metal type and thickness analysis, we further show that the impacts of these two factors on PSHE shifts are mainly subject to HMM thickness.

AbstractThe discovery of Photonic spin Hall effect (PSHE) on surface plasmon polaritons (SPPs) is an important progress in photonics. In this paper, a method of realizing multi-channel PSHE in two-dimensional metal-air-metal waveguide is proposed. By modulating the phase difference $$\phi$$ ϕ and polar angle $$\theta$$ θ of the dipole source, the SPP can propagate along a specific channel. We further prove that PSHE results from the component wave interference theory. We believe that our findings will rich the application of SPPs in optical devices.
