Query: Spin currents of exciton polaritons in a microcavity with (110)-oriented
  quantum well   We study the polarization optical properties of microcavities with embedded
(110)-oriented quantum wells. The spin dynamics of exciton polaritons in such
structures is governed by the interplay of the spin-orbit splitting of exciton
states, which is odd in the in-plane momentum, and the longitudinal-transverse
splitting of cavity modes, which is even in the momentum. We demonstrate the
generation of polariton spin currents by linearly polarized optical pump and
analyze the arising polariton spin textures in the cavity plane. Tuning the
excitation spot size, which controls the polariton distribution in the momentum
space, one obtains symmetric or asymmetric spin textures.
