Free Space Optical Perfect Shuffle Interconnection Based on 4-f Parallel Optical Logic Processor

The amalgamation of parallel optical logic processors and parallel optical interconnections is essential for the rapidly development of the parallel optical computing technologies. According to the light field distribution at the filtering plane and the output plane of the 4-f optical correlator achieved by theory analysis, the 4-f correlator with suitable filtering grating can implement free space optical Perfect Shuffle interconnection perfectly. The experiment results of the left Perfect Shuffle and the right Perfect Shuffle indicate that, based on the 4-f correlators with filtering grating, the parallel optical logic processors and the parallel optical interconnections can be accomplished perfectly by the same optical structure, which may introduce the amalgamation of the parallel optical logic processor and the parallel optical interconnection.
