En este documento, presentamos el modelado de un canal de fibra óptica mediante la resolución de la Ecuación No Lineal de Schrödinger (NLSE). Se presentan las dos formas de solución para la NLSE: la forma analítica y la forma numérica empleando el método SSF (Split–Step Fourier Transform). En la simulación se consideran efectos lineales como la dispersión cromática y los efectos no lineales. Uno de los efectos no lineal es el efecto Kerr, del que se derivan los efectos de auto modulación fase (Self Phase Modulation, SPM) y modulación de fase cruzada (Cross Phase Modulation, XPM). Los métodos de solución son empleados para simular y visualizar los efectos de propagación a través de la fibra óptica. Se analizan los efectos de propagación para un escenario de red de acceso óptica con fibra mono–modo estándar (Single Mode Fiber, SMF), con longitudes de fibra de 20 y 40 km y tasas de bits entre 1,25 y 100 Gbps. De otro lado, son presentados los fenómenos no lineales como dispersión estimulada de Raman (Stimulated Raman Scattering, SRS) y dispersión estimulada de Brillouin (Stimulated Brillouin Scattering, SBS). Se presentan las ecuaciones para modelar SRS. Se presentan resultados de simulación de la amplificación Raman en un escenario seleccionado.

Stimulated Raman

An attempt is made to check by experiment the assumption that the 2nd order Stokes radiation in collinear direction is generated from the primary light by the same mechanism as the 1st order radiation. If is found that the 1st order Stokes beam does not have a sufficiently high intensity over a sufficiently long interaction lenght to explain the generation of the observed 2nd order Stokes radiation as exclusively attributable to this mechanism. An alternative theory is advanced according to which the molecular vibrations generated in the 1st order Stokes process contribute to this effect in the small-signal range. This allows a more plausible explanation of the experimental results. The experiments were performed with benzene at λ = 0.53 μm because this substance exhibits strong stimulated Raman scattering without selffocusing at this wavelenght.
