“…20 Sabadel et al demonstrated that the introduction of elements such as Ba or Ti changed the coordination of Te atoms in the glasses, affecting their physical properties. The authors measured the nonlinear refractive indices and absorption coefficient of four different tellurite glass compositions, using laser pulses with 250 ps, at 532 nm.…”

The third-order nonlinear optical properties of tellurite glasses with different compositions were investigated in the femtosecond regime at 810nm. Using the I-scan technique, positive nonlinear refractive indices of ∼10−15cm2∕W were measured. The authors also determined that nonlinear absorption was negligible for all studied samples. This result, added to their good chemical stability, indicates that tellurite glasses are promising materials for ultrafast photonic applications.

“…In the case of the bulk glass, the spectrum is similar to that reported previously for pure TeO 2 glass 19 and multicomponent tellurite glasses with low content of network modifiers. [20][21][22] The spectrum has been normalized to the intensity of the peak at 660 cm −1 and it clearly shows three different bands, indicated in the figure as A, B, and C. The A band at 400-500 cm −1 and B band at 660 cm −1 are associated to the vibration of symmetric and antisymmetric Te-O-Te linkages, respectively, related to a continuous network built up by ͓TeO 4 ͔ structural units, called trigonal bypyramids. Finally, the C band, at frequencies between 700 and 800 cm −1 , is related to the presence of 4,[19][20][21][22] Besides those peaks, the small band observed at 900 cm −1 is related to the presence of ͓NbO 6 ͔ structural units.…”

Tellurite ͑TeO 2 -TiO 2 -Nb 2 O 5 ͒ thin film glasses have been produced by pulsed laser deposition. The dispersion of the real and imaginary parts of the linear refractive index has been measured in the range from 300 to 1700 nm. Films present high refractive index ͑n = 2.01͒ and reduced absorption ͑k Ͻ 10 −4 ͒ at = 1500 nm. The nonlinear third order optical susceptibility ͉͑ ͑3͒ ͉͒ has been determined at four different wavelengths ͑600, 800, 1200, and 1500 nm͒. The out-of-resonance ͉ ͑3͒ ͉ values ͑ϳ10 −12 esu͒ are found to be ten times higher than those of the bulk glass and 10 2 times higher than that of silica. Compositional and structural analysis reveals an increase of both the Ti atomic content and the fraction of nonbridging oxygen bonds in the deposited films. Both factors lead to a higher hyperpolarizability of the film constituents that is proposed to be responsible for the high ͉ ͑3͒ ͉ value of the films.

“…Tellurium oxide TeO 2 based glasses are highly efficient for the development of optical devices [1][2][3]. Moreover, the assimilation of rare earth ions can stabilize the metastable crystalline phase leading towards widespread applications [4,5].…”
