The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, have been evaluated using the Z-scan technique. Values of n2≈ 10-15 - 10-14 cm2/W of electronic origin were measured and negligible TPA coefficients (β < 0.003 cm/GW) were determined. The response time of the nonlinearity is faster than 100 fs as determined using the Kerr shutter technique. The figure-of-merit usually considered for all-optical switching, T = 2βλ/n2 , indicates that AG are very good materials for ultrafast switches at telecom wavelengths. © 2007 IEEE.293-296engAll-optical switchingAntimony oxide glassesNonlinear refractive indexTelecom wavelengthsAbsorptionAntimonyFiber optic networksGlassLight absorptionLight measurementLight refractionLuminescence of organic solidsMultiphoton processesOptical data processingOptical materialsOptical propertiesOrganic polymersPhotonsRefractive indexRefractometersTelecommunicationTelecommunication systemsAntimony glassesElectronic originsExcitation wavelengthsKerr shuttersNon linearitiesResponse timesScan techniquesTwo-Photon absorptionsUltra fastsUltrafast switchesOptical switchesTrabalho apresentado em evento10.1109/ICTON.2007.4296208Acesso aberto2-s2.0-4834911167129985038419178153349586880746735
