ABSTRACT:
A birefringent structure useful as a waveplate, grating, a hologram, a beam separator, a digital data storage medium or the like is formed by photo-exposure causing photo-reaction between photons and polymeric structures. In a specific embodiment, birefringence is induced by applying optical energy to a polymer film such as a polysilane with sufficient intensity to excite nonlinear absorption in the polymer film such that a pattern of the exposing optical energy is recorded in the polymer film. The optical energy is of a distinct polarization state such that the nonlinear optical ef
