Evanescent - Wave Recording in Very Thin Layers

Abstract

The theoretical background of optical holographic recording in very thin films is given. The interference fringes are stored by surface - propagating evanescent waves. Such waves are created by the total internal light reflection (TIR). The experimental verification of the theory is made. The holographic grating with 454nm period has been recorded in 29, 39 and 74 nm thick As2S3 films. The diffraction efficiency dependence on the time is investigated. The polarization behavior of TIR surface holograms is similar to that of the thick Bragg gratings. The possible applications of this holographic recording are also discussed.
