摘要: We report measurements of the nonresonant nonlinear refractive index n2 in antimony glasses at telecom wavelengths. The were performed using Z-scan technique with a 130fs pulsed laser operating five wavelengths range 1400–1600nm. Values n2≈10−15cm2∕W measured and negligible two-photon absorption coefficient (<0.003cm∕GW) was estimated for all compositions. samples present good figure merit ultrafast all-optical switching.
