RESUMEN

En este trabajo se presenta un modelo matemático que describe rigurosamente la interacción entre esparcimiento Raman estimulado (SRS) y mezcla de cuatro ondas (FWM) en amplificadores Raman distribuidos (DFRAs). Los efectos paramétricos ocurridos en DFRAs debido al proceso de FWM entre bombas, son completamente caracterizados. Los resultados de las simulaciones numéricas son contrastados con mediciones experimentales llevadas a cabo en diferentes configuraciones de DFRAs. Los resultados permiten validar el modelo matemático propuesto, el cual puede ser extendido para incluir otras no-linealidades. Finalmente, se analizan los efectos de FWM entre bombas en el comportamiento espectral de la ganancia de un DFRA.

Palabras clave: Amplificador de fibra Raman distribuido (DFRA), mezcla de cuatro ondas (FWM), redes ópticas WDM, ecualización de potencia.


ABSTRACT

In this work, a comprehensive mathematical model which rigorously describes the interaction between stimulated Raman scattering (SRS) and four-wave mixing (FWM) in distributed fiber Raman amplifiers (DFRAs) is presented. The parametric effects on DFRAs due to pump-pump FWM processes are completely characterized. Numerical simulations are contrasted with experimental measurements which were carried out with different configurations of DFRAs. The results validate the proposed mathematical model, which can be extended to include other non-linear effects. Finally, the pump-to-pump FWM effects on the spectral gain of a DFRA are analyzed.

Keywords: Distributed Fiber Raman Amplifier (DFRA), Four-Wave Mixing (FWM), WDM optical networks, power equalization.
