The distributing formulas of the complex amplitude and the light intensity at output plane are presented in this paper, based on the new method using micro-optical array structure to achieve Perfect Shuffle (PS) transformation presented by us ,using the theories of information optics and binary optics. According to the formulas, the technical design and fabricated parameters are completed and exported. It's indicated that the theoretical analysis and designs accords well with practices in the sequent fabrications and testing experiments. The conclusions of the theoretical analysis in this paper are very important and significative for guiding the realization of optical switching and optical interconnection by using micro optical structure with the diffractive method.

In this paper, a binary optical array element which can realize 8-channel PS transformation is fabricated with very large scale integration (VLSI), stepping photolithography and reactive ion etching (RIE). Using the element, we perform experiments of the PS transformation, tests and analysis. The efficiency and cross talk of each channel are measured when only one channel has been reserved while other channels have been closed. The result indicates that the method proposed to realize the PS transformation by using the micro-optical array element agrees well with theoretical expectation. This success of the experiment lays a good foundation for us to do further research on optical transformation through multilevel interconnection.
