Abstract

The invention provides a frequency-stabilized photoelectric oscillator, and relates to the technical field of microwave photonics. The frequency-stabilized photoelectric oscillator comprises: a light source unit used for emitting a single-frequency optical signal and equally dividing the single-frequency optical signal into two paths; an photoelectric oscillator used for converting the received single-frequency optical signal into a sweep-frequency electric signal and dividing the sweep-frequency electric signal into two paths, wherein one path serves as an output signal to be output, and the other path forms a closed loop; and a frequency stabilization controller used for monitoring the wavelength of the other path of single-frequency optical signal in real time and feeding back and adjusting the single-frequency optical signal emitted by the light source unit, so that the frequency stabilization of the sweep-frequency electric signal output by the photoelectric oscillator is realized.

Description

technical field [0001] The present disclosure relates to the field of microwave photonics technology, in particular to a frequency-stabilized photoelectric oscillator. Background technique [0002] The use of microwave photonics to generate electrical signals has always attracted much attention. The electrical signals generated by traditional electrical methods often have problems such as phase noise difference. With the development of microwave photonic technology, the use of photoelectric oscillators to generate electrical signals has been widely studied. However, the current use of photoelectric oscillators to generate electrical signals has the disadvantage of frequency instability. The frequency stability of the signal. Contents of the invention [0003] (1) Technical problems to be solved [0004] Based on the above problems, the present disclosure provides a frequency-stabilized optoelectronic oscillator to alleviate the technical problems of the prior art that th...
