摘要： The general field of the invention is that of devices for photonic generation of arbitrary microwave signals having linear frequency modulation, including a laser (1), an assembly (2) for shaping the transmitted signal and a photoreceptor (3), the bandwidth of which is in the microwave frequency range. The shaping assembly comprises: a first optical splitter (20); a first optical pathway comprising a frequency-shifted loop including an optical splitter (50), a first optical amplifier (60), an optical isolator (70), a first spectral optical filter (75) and an acousto-optical frequency shifter (80); a second optical pathway comprising an electro-optical frequency shifter (30); a second optical splitter (40); a second optical amplifier (90); and a second optical filter (100); the acousto-optical shifting frequency, the electro-optical shifting frequency and the amplification gain of the first optical amplifier being adjustable.
