Paper Abstract

We demonstrate the effects of the applied field orientation during the writing period in electrical fixing. The dependency of the diffraction efficiency on the direction of the applied electric field while writing a hologram is studied. Our experiments show that during writing, when the electric field is applied opposite to the c-axis the grating can be successfully revealed with both positive and negative dc voltages. However, when the grating is written with a field parallel to the c-axis, the grating can only be revealed with a field applied in the opposite direction. This situation generates the largest diffraction efficiency of nearly 78%. Theoretical analyses of these observed phenomena are performed.
