Evanescent (surface) wave holographic recording in thin polymeric film

Holographic grating recording with surface evanescent waves is reported. Owing to the small penetration depth the interference pattern is sorted in a 200 nm thick polystyrene film, sensitized with ON-stilbene. The absorption distribution in the recording medium is analysed in the small attenuation index approximation. The diffraction efficiency dependence on time and temperature is also investigated.
