Abstract :
A hybrid-multiplexed holographic memory using polarization multiplexing accompanied with angle multiplexing in a LiNbO3 crystal is demonstrated. In the configuration, the signal beams are normal incident on the crystal, and incident angle of the reference beam for recording both TM and TE polarized images is kept around 25deg in the air. The saturation diffraction efficiency for both TM and TE hologram is about 2.6 times 10-2. It was found that the saturation diffraction efficiencies of these two holograms almost keep the same but the writing speeds of these two holograms are different. Experimental results show that diffraction efficiency of each hologram is about 6.5 times 10-5 after scheduled exposure.
