Abstract

The invention discloses a coupled optoelectronic oscillator. The coupled optoelectronic oscillator comprises an FP (Fabry-Perot) laser and an optoelectronic oscillation loop, wherein the FP laser is used for producing multi-longitudinal-mode lasing and sends the multi-longitudinal-mode lasing to the optoelectronic oscillation loop; the FP laser receives injecting signals produced by the optoelectronic oscillation loop, finishes mode locking under the driving of the injecting signals and produces the multi-longitudinal-mode lasing after mode locking; the optoelectronic oscillation loop is used for receiving the multi-longitudinal-mode lasing sent by the FP laser, producing injecting signals and injecting the signals back to the FP laser; further, the optoelectronic oscillation loop receives the mode-locked multi-longitudinal-mode lasing sent by the FP laser and outputs optical pulse signals and microwave signals according to the multi-longitudinal-mode lasing after mode locking. By the aid of the technical scheme, the system size is greatly reduced, the cost is reduced, high-frequency and low-threshold microwave oscillation can be obtained under the condition that a microwave narrow-band filter is not used, and the limitation of the microwave filter to working frequency is eliminated.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mutual coupling photoelectric oscillator. Background technique [0002] As a microwave signal generator with high frequency and low phase noise, the Optoelectronic Oscillator (OEO) plays an important role in the fields of optical fiber communication, wireless communication, radar system, sensing system, high-precision measurement and precision instruments. Value. OEO is a photoelectric hybrid positive feedback oscillating loop, which uses a high-Q, low-loss time-delay fiber as a time delay and energy storage unit, thereby generating high-purity, low-phase-noise microwave signals. A notable feature of OEO is that the phase noise of its output microwave signal has nothing to do with the operating frequency, which is a huge advantage over electronic microwave oscillators. [0003] On the basis of traditional OEO, a coupled optoelectronic oscillator (Coupled Optoelectronic Osc...
