Shift currents in bulk GaAs are computed and analyzed using a microscopic model. Our approach combines k.p band structure calculations with the multisubband Bloch equations and provides a transparent description of the generation and the dynamics of optical material excitations. The description of shift currents requires to include o-resonant excitations into the analysis. Besides sketching our theoretical approach, numerical results on the shift current dynamics are presented and discussed.
