An Improved Algorithm to Solve Erbium Doped Fiber Source Propagation equations
نویسندگان
چکیده
An improved scheme has been developed to solve the standard propagation equations (SPE) for Erbium doped fiber sources (EDFS). The scheme uses Rosenbrock algorithm based on implicit differentiation methods. The profiles of Forward Amplified Spontaneous Emission (FASE), Backward Amplified Spontaneous Emission (BASE) and Pump power along the fiber are presented and compared with the results of conventional fixed step and embedded RungeKutta methods, specifically RK45. 3 The proposed multi-step method is stable even when designing EDFS for fiber lengths at which the above methods fail to converge.

متن کاملModified Split-Step Fourier Method for the Numerical Simulation of Soliton Amplification in Erbium- Doped Fibers with Forward Propagating Noise
Using a modified version of the split-step Fourier method, we analyze the effect of noise on soliton propagation inside erbium-doped fiber amplifiers. In fact, noise from forward-propagating amplified spontaneous emission, associated with a Markov immigration process, is included in the analysis of soliton amplification. Moreover, this algorithm accounts for the real spectral gain profile of th...
