Implementation of FPS interconnection network using 2-D grating

Perfect shuffle is one kind of essential interconnection network which can be used to realize the optical interconnection in arbitrary form. In this paper, a new method using 2-D diffraction grating to implement the FPS(folded perfect shuffle) interconnection network was proposed. The principle of this method was described. Experiments were conducted using this method, and experimental results were presented. It was shown that this method is simple, feasible and effective.
