  We present the transfer of the spatially variant polarization of
topologically structured light to the spatial spin texture in a semiconductor
quantum well. The electron spin texture, which is a circular pattern with
repeating spin-up and spin-down states whose repetition rate is determined by
the topological charge, is directly excited by a vector vortex beam with a
spatial helicity structure. The generated spin texture efficiently evolves into
a helical spin wave pattern owing to the spin-orbit effective magnetic fields
in the persistent spin helix state by controlling the spatial wave number of
the excited spin mode. By tuning the repetition length and azimuthal angle, we
simultaneously generate helical spin waves with opposite phases by a single
beam.
