Fabrication of birefringent gratings using nonlinear polysilane thin films

Birefringence is shown to be induced in polysilane thin films by the process of chain scission induced by nonlinear absorption at visible wavelengths. This writable birefringence is easy to control and can be used for the fabrication of birefringent gratings and other optical devices.
