We report an optoelectronic feedback loop that permits the active stabilization of an interferometric setup for any chosen Value of the phase between the interfering beams. This method is based on phase modulation and homodyne detection techniques. The phase can be stabilized with a precision of better than 1 deg for our experimental conditions.20663563
