The present paper is the reply to Sandu's Comment on our paper [Phys. Rev. B 72, 153314 (2005)], i.e., the effect of the current operator on the spin-dependent tunneling through a barrier in the presence of the Dresselhaus spin-orbit interaction (DSOI). We demonstrate theoretically and numerically that our previous numerical result is correct when there is no DSOI in the contact region and it remains a good approximation in the presence of the k(3)-DSOI in the contact regions.
