Effect of ZnO and Bi2O3 addition on linear and non-linear optical properties of tellurite glasses

Abstract

Glasses in the system TeO2-Bi2O3-ZnO were studied with respect to their linear refractive indices and optical absorption in the UV-vis range. The third order non-linear refractive indices were measured using degenerated four wave mixing (DFWM). The optical Kerr susceptibilities calculated hereof were in the range from 5.49 to 6.58 × 10-13 esu and hence 34-41 times larger than that of fused SiO2. They are roughly proportional to values theoretically calculated by the theory of Lines. © 2006 Elsevier B.V. All rights reserved.
