Determination of resonance frequencies in silica fiber using SRS gain

This paper presents a novel approach for the determination of resonance frequencies in silica fiber using composite susceptibility model and Stimulated Raman Scattering (SRS) gain. The Raman gain coefficient in silica fiber is calculated in terms of composite susceptibility model where resonance frequencies of material are considered. Composite susceptibility is optimized using Genetic Algorithm to match calculated gain with the experimental results and, hence eight resonance frequencies are found.
