Abstract: The light pulse generator includes a source for generating a light beam, an electroabsorbent modulator for modulating the light beam into light pulses, and means for applying voltage control to the modulator. The electroabsorbent modulator includes at least two doped layers and between them at least one intermediate layer that is made of a material that is not intentionally doped, and that has an electroabsorbent material included therein. The absorbent or transparent state of the intermediate layer is controlled by a voltage applied between two of the doped layers that have doping of the same sign, the transmissivity of the modulator as a function of the voltage controlling it being at a maximum in the vicinity of zero volts and being symmetrical thereabout.
