The amorphous chalcogenide glass Sn{sub 1}As{sub 20}S{sub 79} is demonstrated to undergo permanent changes in refractive index on irradiation with ultraviolet light. The refractive properties of this material and the effect of annealing at temperatures below the glass transition temperature are investigated in detail. An Sn{sub 1}As{sub 20}S{sub 79} strip waveguide is fabricated using this photoinduced refractive index change, and the device is shown to function as expected with good propagation characteristics for the 632.8 nm guided mode.
