A variable chirp electro-optic modulator (12) is provided that uses a single modulation signal. The modulator has several optical paths in the proximity of one or more modulation electrodes which are driven equally by a single modulation source (14). The amount of chirp desired of the modulator is controlled by varying the optical amplitude or phase of the light in the different paths.

Modulateur optoélectronique (12) à compression d'impulsions variable mettant en application un seul signal de modulation. Ce modulateur possède plusieurs trajets optiques à proximité d'une ou de plusieurs électrodes de modulation commandées de façon égale par une seule source de modulation (14). On commande le niveau de compression d'impulsions en modifiant l'amplitude optique ou la phase de la lumière dans les différents trajets.
