“…Third-order optical nonlinearities (TONL) of glass materials have been extensively studied, mainly due to their possible applications in telecommunications as ultrafast optical switches, modulators, and electro-optical devices [1][2][3][4]. Among several formed glass lattices, TeO 2 -based glass is receiving special attention due to its good optical properties, particularly when compared to traditional silicate glass, for instance.…”

We studied the influence of different lattice modifiers (Nb 2 O 5 , Bi 2 O 3, or TiO 2) on the nonlinear refractive index of a tellurite glass matrix by using the Z-scan technique. Based on the ability of the lattice modifiers to decrease the band-gap energy while simultaneously increasing the linear refractive index of the TeO 2-based glass, we investigated how these modifiers affect the nonlinear refractive indices. All studied glass presented high nonlinearities, and the addition of lattice modifiers made only a small contribution to increasing magnitude. These results could be explained through the observation of the band-gap energy reduction, which is related to the increase in the non-bridging oxygen content with the addition of the lattice modifier. The increase in the refractive index nonlinearity is explained by the optical basicity and the high electronic polarizability of the modifiers ions.

“…The same kind of nonlinear results (i.e., SA in OA Z-scan mode and negative nonlinear refraction in CA Z-scan mode) were reported by Chen et al [39] recently and they reported their investigations on transparent glasses matrix with glass composition of 60Bi 2 O 3 -30B 2 O 3 -10TiO 2 in which they measured the NLO properties by adopting Z-scan technique at 750 nm using 200 fs laser pulses and a repetition rate of 76 MHz. The 2PA coefficients (α 2 ) of Au-NP-doped glasses of present investigation are found to be one order of magnitude greater than that of Na 2 O-CaO-B 2 O 3 -SiO 2 bulk glasses embedded with CuO quantum dots (α 2 = 1.56 × 10 −12 m/W at 1550 nm) [32] and that of gold NP-doped heavy metal oxide glasses (α 2 varied from 0.6 × 10 −12 m/W to 0.9 × 10 −12 m/W for the wavelengths in the range of 500 nm to 580 nm) [22]. The coefficients are comparable to that of sodium borosilicate glasses doped with copper quantum dots (α 2 = 2.10 × 10 −11 m/W at 1550 nm) [21] and lower than that of silver-doped oxyfluoride glasses (α 2 ranges from 1.1 × 10 −9 m/W to 24.8 × 10 −9 m/W at the wavelengths from 445 nm to 660 nm of NPs sizes 3 nm and 17 nm) [39].…”

“…Zhong et al [21] reported reverse saturable absorption (RSA) in copper NPdoped sodium borosilicate glasses at 800 nm with fs-pulse excitation. Furthermore, by studying the temporal dynamics of HMO glasses embedded with Au-NPs using Kerr gate measurements at 780 nm using 120 fs pulses, Almedia et al [22] have found that the response time was 220 fs (which was faster than the pulse duration). However, there are very few reports on the comparison of NLO properties using different wavelengths in glasses.…”

Optical glasses possessing large third-order optical nonlinear susceptibility and fast response times are promising materials for the development of advanced nonlinear photonic devices. In this context, gold nanoparticle (NP)-doped borate glasses were synthesized via the melt-quench method. The nonlinear optical (NLO) properties of thus prepared glasses were investigated at different wavelengths (i.e., at 532 nm using nanosecond pulses, at 750 nm, 800 nm, and 850 nm wavelengths using femtosecond, MHz pulses). At 532 nm, open aperture (OA) Z-scan signatures of gold NP-doped borate glasses demonstrated reverse saturable absorption (RSA), attributed to mixed intra-band and interband transitions, while in the 750-850 nm region, the OA Z-scan data revealed the presence of saturable absorption (SA), possibly due to intra-band transitions. The NLO coefficients were evaluated at all the spectral regions and further compared with some of the recently reported glasses. The magnitudes of obtained NLO coefficients clearly demonstrate that the investigated glasses are potential materials for photonic device applications.
