Abstract
We study tellurite glasses as the Raman gain media for the soliton self-frequency shift (SSFS). The Raman response function, Raman fraction, and Raman time constant of tellurite glasses are obtained from the Raman gain spectra. We evaluate the performance of SSFS based on the Raman gain coefficient spectra and generalized nonlinear Schrödinger equation. Our results show that the amount of SSFS is directly proportional to the Raman time constant. The most efficient tellurite glass for SSFS is clarified. It is shown that the tellurite glasses are promising materials for nonlinear optics applications.
