To carry out the regeneration of binary optical signals, the device includes a first level (1) to provide a modulation signal (B), the high levels of which are stabilized to depend very little on the fluctuations of the input signal. The signal (B) is applied to a second level (2) comprising an interferometric structure (7) designed to provide an output signal (S) resulting from interference, either constructive or destructive, from the first and second auxiliary waves, respectively, (AM1, AM2) when the power of the modulation signal (B) corresponds to a first or second binary state, respectively. The device may be used to modify the input signal, either by deletion or insertion of data. It applies to optical data connection or transmission.
Pour réaliser la mise en forme de signaux optiques binaires, le dispositif comporte un premier étage (1) pour fournir un signal modulant (B) dont les niveaux hauts sont stabilisés pour être peu dépendants des fluctuations du signal d'entrée. Le signal (B) est appliqué à un second étage (2) comportant une structure interférométrique (7) conçue de façon à fournir un signal de sortie (S) résultant d'une interférence respectivement constructive ou destructive de première et seconde ondes auxiliaires (AM1, AM2) lorsque la puissance du signal modulant (B) correspond respectivement à un premier ou à un second état logique. Le dispositif peut servir à modifier le signal d'entrée par effacement ou insertion de données. Application à la commutation ou à la transmission de données optiques
