Raman-Induced Asymmetric Pump Noise Transfer in Fiber-Optical Parametric Amplifiers
Journal article, 2010
In this paper, a theoretical model accounting for the asymmetric transfer of pump noise in the gain spectrum of a single pump fiber parametric amplifier due to the Raman effect is presented. The model is satisfactorily verified by the experiments. The experiments demonstrate that the pump electrical SNR (ESNR) remains unchanged in contrast to the optical SNR (OSNR) which decreases along the fiber.
