We propose a mechanism to couple spin-resolved edge states in the integer quantum Hall effect by employing an array of voltage-controlled top gates. Strong enhancement of the coupling is achieved when the array periodicity matches the inverse of the wave-vector difference of the two states involved. Well known techniques of separately contacting the edge states make possible to selectively populate and read-out the edge states, allowing full spin read-out. Our device represents the quantum Hall version of the all-electrical Datta-Das spin-field effect transistor.
