ABSTRACT
We report on the ultrafast nonlinearity of antimony polyphosphate glasses measured using the Kerr shutter technique. The nonlinear refractive index, n[sub 2], was (1.1±0.2)×10[sup -14] cm[sup 2]/W at 800 nm, and enhancement of n[sub 2] by ≈80% was observed by adding 10% of lead oxide in the glass composition. The full width at half-maximum of the third-order correlation signal was 150 fs, which implies a fast response of the samples (<=100 fs). Nonlinear absorption was negligible in the range of intensities used. © 2003 American Institute of Physics.

    Refractive indices of fluoride glass fibers were measured for the first time and a remarkable decrease in the refractive index during fiber fabrication processes has been observed. This decrease is most likely due to the change in the glass structure during fiber drawing and due to the stress...
