RAMAN amplifier gain dynamics with ASE : Numerical analysis and simulation approach
Spontaneous Raman scattering add up with the amplified signal and reflect as a noise because of random phases linked with all spontaneously generated photons. The amplified spontaneous emission noise in systems with distributed Raman gain for single pump amplification is diagnosed numerically and simulated using MATLAB to obtain experimental outcome. The signal gain of Raman Amplifier as a function of fiber length and pump power is elaborated. The noise accompanying an optically amplified signal plays an important role for understanding the basic properties of the gain medium. So in this work, we demonstrate an analytical formalism and a numerical horizon of the amplified spontaneous emission (ASE) noise power for distributed Raman amplifier (DRA).
