| 摘要 |
The invention concerns a device comprising a source of two coherent beams (1A) sending a first beam (F1) to a modulator (4) receiving a modulating electric signal (S(t)), the modulator being connected to a first input of a gain optical fiber amplifier (7), and sending a second beam (F2) to a second input of the amplifier, which is in pumping configuration. A reduced-carrier modulated wave can be collected by means of an optical coupler on the amplifier second input.
