Query: Spin photonics and spin-photonic devices with dielectric metasurfaces   Dielectric metasurfaces with spatially varying birefringence and high
transmission efficiency can exhibit exceptional abilities for controlling the
photonic spin states. We present here some of our works on spin photonics and
spin-photonic devices with metasurfaces. We develop a hybrid-order Poincare
sphere to describe the evolution of spin states of wave propagation in the
metasurface. Both the Berry curvature and the Pancharatnam-Berry phase on the
hybrid-order Poincare sphere are demonstrated to be proportional to the
variation of total angular momentum. Based on the spin-dependent property of
Pancharatnam-Berry phase, we find that the photonic spin Hall effect can be
observed when breaking the rotational symmetry of metasurfaces. Moreover, we
show that the dielectric metasurfaces can provide great flexibility in the
design of novel spin-photonic devices such as spin filter and spin-dependent
beam splitter.
