摘要： 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.

摘要： An emitter emits a wavelength included in the visible and/or infrared spectrum to illuminate a scene. An observation system is configured to deliver an image representative of the illuminated scene to an observer. The emitter is configured to deliver a light emission by at least one flash with a luminous power greater than a threshold generating dazzling. The observation system presents a first operating condition and a second operating condition of the observed scene to the observer, the second operating condition transmitting less luminous power than the first operating condition. A synchronization circuit is configured to synchronize the emitter and the observation system so that the observer is not dazzled during the emission phase of the emitter.

This component includes an InP substrate, a laser (L) formed from a stack of semiconductor layers epitaxied on the substrate, including an active and absorbent layer and a periodic Bragg grating fixing the emission wavelength of the laser to a value slightly above an optimum wavelength of the laser gain peak. An electrooptical modulator (M) is formed from the same stack of semiconductor layers, with the exception of the Bragg grating, the active layer of the laser and the absorbing layer of the modulator being formed by the same epitaxied structure having several constrained or unconstrained quantum wells, the modulator functioning according to a confined Stark effect. The semiconductor layers of the laser and those of the modulator are electrically controlled.
