%X Quantum interference control photocurrent in bulk semiconductors is analyzed using the Fermi golden rule and Kane six-band model. The initial momentum distributions of photoexcited carriers in different polarized light fields are calculated. The polarization dependence of the coherent currents is shown explicitly in a microscopic level. For the case of parallel linear polarizations, the current direction is along the direction of the light polarization; while for the case of perpendicular polarizations the current direction is along the polarization of the harmonic frequency light. It is also shown that when the one-photon transition and the two-photon transition is balanced, the maximum current injection efficiency is achieved.
