We propose a scheme for the generation of photocurrent in bent quantum wires.We calculate the current using a generalized Landauer-Buttiker approach thattakes into account the electromagnetic radiation. For circularly polarizedlight, we find that the curvature in the bent wire induces an asymmetry in thescattering coefficients for left and right moving electrons. This asymmetryresults in a current at zero bias voltage. The effect is due to the geometry ofthe wire which transforms the photon angular momentum into translational motionfor the electrons
