Abstract | The invention relates to a photoelectric oscillator with a microwave amplitude limiter. The photoelectric oscillator comprises a light source and a photoelectric loop, and the photoelectric loop comprises a light modulator, a long fiber, a light detector, a microwave amplifier, the microwave amplitude limiter, a microwave coupler, a microwave bandpass filter and a microwave phase shifter. Compared with a routine photoelectric oscillator, the microwave amplitude limiter is used in the photoelectric loop for the first time. The photoelectric loop is a nonlinear device, and limits the amplitude of output microwave signals, so that the microwave amplifier works in a linear area, and phase-noise deterioration of output signals of the oscillator caused by that the microwave amplifier works in a saturation area can be avoided. Compared with the routine photoelectric oscillator which does not include the microwave amplitude limiter and whose microwave amplifier works in the saturation area, the photoelectric oscillat |
