초록

The chalcogenide glasses of thin films have superior property of the photoinduced anisotrophy(PA). In this study, we observed the phenomenon of Ag polarized photodoping using the irradiation with polarized He-Ne laser light, in the thin film of chalcogenide As/sub 40//Ge/sub 10//Se/sub 15//S/sub 35/ and the double-layer of Ag doped As/sub 40//Ge/sub 10//Se/sub 15//S/sub 35/. The Ag polarized photodoping result in reducing time of saturation anisotrophy and increasing sensitivity of linearly anisotrophy intensity, up to maximum 220%. In the thin films of chalcogenide, the Ag polarized photodoping will be show a capability of new method that suggested more improvement of photoinduced anisotrophy property
