The photonic spin Hall effect, originating from photonic spin-orbit interactions, has attracted considerable research interest due to its potential for applications in spin-controlled nanophotonics. However, most research efforts have focused only on 1D modulation, including transverse or longitudinal spin-dependent splitting. Here, a novel method is proposed for multidimensional spin-dependent splitting on a single-layer dielectric metasurface. Due to the interplay of the Pancharatnam-Berry phase and dynamic phase, the longitudinal focusing and transverse shifting of the different spin state photons can be simultaneously achieved. Moreover, the conjugated characteristic of the modulated phases of Pancharatnam-Berry phase metasurfaces for different spin photons can be broken, and both symmetric and asymmetric transverse spin-dependent splitting are obtained with the proposed method. This method can be used for the multidimensional and flexible manipulation of spin photons and has potential in spin-controlled nanophotonics, ranging from optical communication to beam shaping and optical sensors.
