Abstract

Apparatus for reshaping a train of light pulses includes an electro-absorbent modulator to which the train of pulses is applied for the purpose of being resynchronized and reshaped. A periodic signal generator that is adjustable in phase and frequency applies a periodic signal to the modulator to voltage control said modulator. Servo-control means control said generator in phase and in frequency to minimize the mean photocurrent delivered by the modulator while it is both in its absorbent state and receiving a light pulse. The apparatus may also be used to recover a periodic signal that is synchronized on a train of modulated light pulses. The invention is applicable to long distance telecommunications by transmitting soliton pulses along optical fibers.
