Electric-Field Multiplexing of Volume Holograms in LiNbO 3

Abstract
The possibility of multiplexing holograms in LiNbO3 by means of an applied electric field is investigated experimentally. The effect of an applied electric field on the recording of holographic gratings as well as on the Bragg condition for previously stored ones is studied in the reflection geometry. The conclusion is that two image holograms can be addressed using an electric field. This multiplexing is shown experimentally.
