摘要
In this paper, ASE (amplified spontaneous emission) noise induced by parametric gain and spontaneous Raman scattering in optical fiber Raman amplifier is analyzed. Expressions regarding the generation and amplification of such kind of noise are present. Simulations are carried out on a forward WDM pumping fiber Raman amplifier and a long haul transmission system with multi-stage fiber Raman amplifiers. Results show that parametric gain induced ASE noise is the main part of ASE noise. Its spectrum is wider and its power is higher than those of spontaneous Raman scattering induced ASE noise.
