Abstract

This paper proposes a fabrication method for realizing all-optical AND and NOR logic gates based on polarization holography. During the recording process, two specially designed polarization holograms are recorded at the dual-region position of the polarization-sensitive material. During the reconstruction process, two reading waves in different directions are used as two input lightwaves. The background lightwave is added to the propagation direction of the two reconstructed waves, and the two reconstructed waves superimposed with the background lightwave are used as two output lightwaves. The light intensity of the two output lightwaves, together, defines the logic signal of the final output. The all-optical AND and NOR logic gates fabricated using this method have the advantages of simple structure, low cost, and fast response.
