Abstract

Optical fiber induced noise limits the noise performance of several radio frequency (RF) over fiber links. In this work, we characterize the effects of Rayleigh scattering on the intensity and phase noise of RF signals transmitted via optical fibers. In addition, we investigate laser frequency modulation as a means of suppressing Rayleigh-induced RF intensity and phase noise. We find the optimal frequency range for laser frequency modulation and demonstrate up to 30 dB suppression of fiber induced noise.
