| Abstract: | The nonlinear refractive index, n2, of films based on the new glass system Sb2O3–Sb2S3 was measured at 1064 nm with laser pulses of 15 ps, using a single-beam nonlinear image technique in presence of a phase object. The films were prepared from bulk glasses by RF-sputtering. A large value of n2 = 3 × 10?15 m2/W, which is three orders of magnitude larger than for CS2, was determined. The result shows the strong potential of antimony–sulfide glass films for integrated nonlinear optics. |
