Electroabsorbent modulator and optical pulse generator comprising it.

摘要

P The electroabsorbent modulator comprises at least two doped layers (11a, 11b, 12) and at least one intermediate layer (13a, 13b) interposed between these two layers in a non-intentionally doped material in which is included an electroabsorbent material, l absorbent or transparent state of this intermediate layer (13a, 13b) being controlled by a voltage (V) applied between two (11a, 11b) layers, which have a doping of the same sign, the transmission of the modulator according to the voltage (V) which controls it being maximum in the vicinity of the zero voltage and symmetrical with respect thereto. BR/ The optical pulse generator comprises a source for generating a light beam, an electroabsorbent modulator of the aforementioned type for modulating this light flux into optical pulses, means for controlling the voltage modulator. / P
