Apparatus for reshaping an optical pulse train and device for recovering a synchronized periodic signal on a modulated optical pulse train.

摘要

The device for reshaping an optical pulse train comprises an electroabsorbent modulator (11) on which the pulse train is sent to be resynchronized and reshaped; a phase and frequency adjustable periodic signal generator (12) which supplies to this modulator (11) a periodic signal which controls this modulator (11) in voltage; servo means (13) controlling this generator 12 in phase and in frequency, so that the average of the BR/ (CF DRAWING IN BOPI) BR/ BR/ in its absorbing state and that it receives an optical pulse, which is minimal. BR/ This device can also be used for the recovery of a synchronized periodic signal on a modulated optical pulse train. BR/ Application to long distance telecommunication by transmission of soliton pulses by optical fibers.
