PHOTONIC GENERATION DEVICE FOR ARBITRATIC FREQUENCY LINEAR MODULATION MICROWAVE SIGNALS

摘要

The general field of the invention is that of photonic generation devices of arbitrary linear frequency modulated arbitrary microwave signals comprising a laser (1), a set (2) for shaping the emitted signal and a photoreceptor (3) whose band passing is in the field of microwave frequencies. The shaping assembly comprises: a first optical separator (20); A first optical channel comprising a frequency shift loop comprising an optical splitter (50), a first optical amplifier (60), an optical isolator (70), a first spectral optical filter (75) and an acousto shifter (80); -optic of frequencies; A second optical channel comprising an electro-optical frequency shifter (30); A second optical separator (40); A second optical amplifier (90); A second optical filter (100); the acousto-optical offset frequency, the electro-optical offset frequency and the amplification gain of the first optical amplifier being adjustable.
