A device is used for generating error signals for regulating the optical alignment of two lightwaves in connection with coherent heterodyne reception and comprises a receiver device ( ) arranged focused opposite a front face at the end of a lightwave fiber ( ) in order to make possible the transmission of the received information lightwave through the lightwave fiber ( ) to an optical waveguide coupler ( ), which is connected via a further lightwave fiber ( ) with a local laser ( ) and via two further lightwave fibers ( ) with respectively one detector ( ) for generating at least one error signal (Sr). A piezoelectric deflection unit ( ) acts on this front face of the lightwave fiber ( ) located in the focusing area of the receiving device.
