Query: Focused linearly-polarized light scattering from a silver nanowire:
  Experimental characterization of optical spin-Hall effect   Spin-orbit interactions (SOI) are a set of sub-wavelength optical phenomenon
in which spin and spatial degrees of freedom of light are intrinsically
coupled. One of the unique example of SOI, spin-Hall effect of light (SHEL) has
been an area of extensive research with potential applications in spin
controlled photonic devices as well as emerging fields of spinoptics and
spintronics. Here, we report our experimental study on SHEL due to forward
scattering of focused linearly polarized Gaussian and Hermite-Gaussian
($\textrm{HG}_{10}$) beams from a silver nanowire (AgNW). Spin dependent
anti-symmetric intensity patterns are obtained when the polarization of the
scattered light is analysed. The corresponding spin-Hall signal is obtained by
computing the far-field longitudinal spin density ($s_3$). Furthermore, by
comparing the $s_3$ distributions, significant enhancement of the spin-Hall
signal is found for $\textrm{HG}_{10}$ beam compared to Gaussian beam. The
investigation of the optical fields at the focal plane of the objective lens
reveals the generation of longitudinally spinning fields as the primary reason
for the effects. The experimental results are corroborated by 3-dimensional
numerical simulations. The results lead to better understanding of SOI and can
have direct implications on chip-scale spin assisted photonic devices.
