Abstract

We show that one-photon absorption of linearly polarized light should produce pure spin currents in noncentrosymmetric semiconductors, including even bulk GaAs. We present 14×14 k·p model calculations of the effect in GaAs, including strain, and pseudopotential calculations of the effect in wurtzite CdSe.
