Abstract

The invention provides a light and small type ultra-low phase noise photoelectric oscillator and an optical micro-cavity manufacturing method thereof. The oscillator comprises a laser, an electrooptical modulator, an optical micro-cavity, a photoelectric detector, an electric amplifier, an electric filter and an electric coupler. An optical signal output by the laser is subjected to modulation and output by the electrooptical modulator, the optical signal amplification by the optical amplifier, optical delay and optical energy storage by the optical micro-cavity, and the photoelectric conversion by the photoelectric detector. The converted electric signal passes the electric amplifier and the electric filter, and is fed back to the electrooptical modulator through the electric coupler. According to the invention, by use of the photoelectric link de-noising technology, and taking low-loss and high Q value optical micro-cavity as an energy storing element, ultra-low phase noise of the microwave signals output by the photoelectric oscillator is achieved; and by use of the micro type optical micro-cavity, small and light photoelectric oscillator is achieved.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a light and small ultra-low phase noise optoelectronic oscillator and a method for manufacturing the same. Background technique [0002] High-performance microwave oscillation signal source is a key component of equipment such as radar, information countermeasures, communication and modern electronic instruments. In the array radar, the high-performance signal source can improve the improvement factor of the radar, filter and reduce the influence of clutter, enhance the weak signal detection ability, improve the speed measurement accuracy and reduce the interference of adjacent band signals; more prominently, the radar signal source The phase noise index has gradually become the technical bottleneck for detecting slow, small and stealthy targets under clutter; therefore, it is very important and urgent to further improve the phase noise performance of microwave oscillatio...
