Embodiment Construction

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0035] The present invention aims to provide a photoelectric oscillator capable of realizing low-phase-noise single-mode stable output of microwave oscillating signals, which is realized by combining injection phase-locking and pilot frequency control technologies. Specifically, side-mode suppression is realized by using injection phase-locking. To ensure single-mode output, pilot frequency control technology is used to overcome the influence of the environment on the photoelectric oscillator to achieve stable output.

Abstract

The invention discloses a photoelectric oscillator, which includes a laser for outputting an optical carrier. The laser is connected to form a photoelectric circulation loop of a photoelectric hybrid resonator. The photoelectric oscillator also includes a laser for injecting a locking signal into the photoelectric circulation loop to realize edge The injection phase-locking module for mode suppression and the stability control module for pilot frequency control to compensate the delay fluctuation of the photoelectric loop. The invention realizes side mode suppression by setting an injection phase-locking module and injecting a locking signal into the photoelectric circulation loop, and by setting a stability control module to extract delay fluctuations of each device in the photoelectric circulation loop and perform corresponding delay fluctuation compensation to achieve stability The purpose of the oscillation frequency is to realize the low phase noise single-mode stable output of the photoelectric oscillator, and because the cyclic oscillation locked by the pilot frequency control and the injection locking signal is carried out in different frequency bands, mutual interference is avoided, and the noise of the control circuit is effectively avoided Parasitic effects on oscillating signals.

Description

technical field [0001] The present invention relates to the field of oscillators, in particular to a photoelectric oscillator. Background technique [0002] Opto-electronic Oscillator (OEO) is a new type of oscillator combining microwave and photonic technology. It has received high attention because of its extremely low phase noise in microwave and millimeter wave frequency bands. Electronic warfare, precision measurement and other fields.
