OPTOELECTRONIC INTERFACE COMPRISING A DIGITALLY SERVO-CONTROLLED ELECTROOPTICAL MODULATOR

摘要

The invention concerns a method for electrooptical modulation which consists in applying on an electrooptical modulator (110) a control signal indexed on a reference value (Vdc), method which consists in sampling (400) the light at the output of a modulator (110, 120) subjected to said reference value and in deducing from said sampled light a signal which is analyzed (210) to update the reference value (Vdc). The invention is characterized in that it consists in converting the sampled light into a digital signal, and in digitally analyzing said signal (220) for updating the reference value (Vdc).
