Precise measurements and analysis of linear and nonlinear optical properties of glass materials near 1.5 μm

Nonlinear optical susceptibility of multicomponent tellurite thin film glasses

“…The value of n measured for the bulk glass is in good agreement with those previously reported for TeO 2 -TiO 2 and TeO 2 -Nb 2 O 5 binary glasses 8,25 and other glasses of the ternary system TeO 2 -TiO 2 -Nb 2 O 5 . 7 The smaller value of n in the case of film glasses could be related to the compositional variations observed in the films ͑Table I͒, which consist mainly in an enrichment in Ti.…”

“…4 Beside these remarkable properties, they stand out for their large nonlinear optical response, as they show some of the highest values of nonlinear refractive index among oxide glasses, which are 10-100 times larger than that of fused silica. [3][4][5][6][7][8] These high values are essential for the development of active nonlinear photonic devices, such as all-optical switches or modulators. 1,2,5,6 However, the successful application of these materials depends not only on their excellent optical properties but also on the capability of producing them in functional configurations such as fibers or thin films.…”

The effect of CdS addition on linear and non-linear refractive indices of glasses in the system TeO2/Nb2O5/ZnO

“…Then, the lone pair occupies the apex of the sp 3 hybrid orbital. The effect of conditional glass formers, such as Nb 2 O 5 is reported to be qualitatively the same as that of network modifiers, however, the effect is not as pronounced [28,6]. From wide angle X-ray and neutron scattering, Table 2).…”

“…In the literature, non-linear refractive indices are reported for a large number of glass systems [4,8,28,6,[29][30][31][32]. In the TeO 2 -SiO 2 system, v (3) -values in the range from 2.4 to 3.8 Â 10 À13 esu were given in [32].…”

“…It was reported that such additions lead to remarkable changes in the physical, especially the optical properties [4]. Hence, these glasses are regarded as promising optical materials for up conversion lasers and non-linear optical materials, which exhibit high third order non-linear optical susceptibilities [5,6].…”
