Abstract

We have investigated the photoinduced birefrinence by the electric field effects in chalcogenide thin films. The electric field effects have investigated the various applied bias voltages(forward and reverse) in chalcogenide thin films. A pumping (inducing) and a probing bean were using a linearly polarized He-Ne laser light (633nm) and semiconductor laser light (780nm), respectively. The result was shown that the birefringence had a higher value in DC +2V than the others, Also, we obtained the birefringence in the electric field effects by various voltages. In addition, we have discussed the anisotropy property of chalcogenide thin films by the electric field effects.
