The 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 (2, 3, 4) arranged focused opposite a front face at the end of a lightwave fiber (1) in order to make possible the transmission of the received information lightwave through the lightwave fiber (7) to an optical waveguide coupler (6), which is connected via a further lightwave fiber (13) with a local laser (12) and via two further lightwave fibers (8, 9) with respectively one detector (10, 11) for generating at least one error signal (Sr). A piezoelectric deflection unit (5) acts on this front face of the lightwave fiber (7) located in the focusing area of the receiving device.
