Photoreversible birefringence is demonstrated in Vycor glass, doped with nanocrystalline ZnS and Cu, by linearly polarized 266-nm pulsed excitation. The birefringence is readily reversed by exposure to orthogonally polarized UV radiation. Photoinduced birefringence is stable at room temperature and can be removed by annealing at temperatures above 250 °C.
