Abstract

High holographic storage capacity of paraelectric K1xLixTa1−yNbyO3:Cu,V using the voltage-controlled photorefractive effect is experimentally demonstrated. Measurements of the M/# for various writing angles and reading fields are presented. In particular, it is shown that 128 angularly multiplexed holograms, written by two plane-wave beams separated by an angle of 8°, yield an M/# of 20.

Diffraction efficiency of 32 holograms written in a field of 2.1 kV/cm and read under different applied fields. The first row was read under the same field as the writing field, the second row was read under the opposite field, i.e., −2.1kV/cm, and the last row was read under a field of −2.8 kV/cm.
