Abstract

Recently experiments have been reported in which logical operations were performed using electric field induced interferences of holograms stored in persistent spectral hole-burning media [1,2]. In principle, the logical operations AND and XOR are sufficient to realize a binary computer [3]. Here a ripple carry full adder [3] for the parallel addition of two sets of 400 binary coded 4-bit numbers is experimentally demonstrated.
