ABSTRACT:
Method and device for generating optical pulses.
According to the invention, in order to generate an optical signal in the form of optical pulses, a semiconductor laser (2) is made to function as gain commutation, and a portion of the light produced by this laser is reinjected into the laser. The light to be reinjected is previously filtered by an optical filter (12) which is tuned to one of the modes of the laser. Another portion of the light produced by the laser is used as an optical signal after having been filtered this portion by the optical filter.
