Optical nonlinearities of tellurite glasses with ultrawide Raman bands
Optical nonlinearities of tellurite glasses with ultrawide Raman bands
Many multicomponent tellurite based glass systems containing heavy metal oxides, alkaline earth oxides and P2O5 with ultrawide Raman bands promising for Raman amplifiers have been designed and fabricated. The third order nonlinear optical susceptibility (χ(3)) is one of the key parameters deciding the Raman gain coefficient and is also useful for many optical processes including optical switching. Therefore, it is very important to have an estimate of the value of χ(3) for this new category of glass compositions. χ(3) of the above mentioned tellurite based glass systems have been measured using the third harmonic generation (THG) and are discussed in this paper. The relation between linear refractive index and χ(3) is also discussed briefly. The tellurite glasses fabricated in the present study have χ(3) values as high as 225 x 10-14 esu, whereas χ(3) of silica glass is 2.8 x 10-14 esu.

Abstract
Many multicomponent tellurite based glass systems containing heavy metal oxides, alkaline earth oxides and P2O5 with ultrawide Raman bands promising for Raman amplifiers have been designed and fabricated. The third order nonlinear optical susceptibility (χ(3)) is one of the key parameters deciding the Raman gain coefficient and is also useful for many optical processes including optical switching. Therefore, it is very important to have an estimate of the value of χ(3) for this new category of glass compositions. χ(3) of the above mentioned tellurite based glass systems have been measured using the third harmonic generation (THG) and are discussed in this paper. The relation between linear refractive index and χ(3) is also discussed briefly. The tellurite glasses fabricated in the present study have χ(3) values as high as 225 x 10-14 esu, whereas χ(3) of silica glass is 2.8 x 10-14 esu.
