  • In order to improve configuration of a widely tunable low-frequency optical radio frequency(RF) generation system and reduce phase noise of the system, a simplified system design was demonstrated with fewer components and improved phase noise performance by using an amplitude modulator. After theoretical analysis and experimental verification, the data of system phase noise and frequency offset was obtained under low-frequency radio signal conditions. The results show that, excess phase noise due to acoustic vibrations of optical fibers can be successfully eliminated by mechanical isolation. The study has some value and practical significance in the field of optical communication in the future.
