Paper Abstract

In this paper, we study the constructions and mathematical expressions of butterfly interconnections and networks. Because 2-D and 3-D networks have different constructions, we discuss the transform from 3-D forms to 2-D ones. We start with optical Fourier transforms to derive the discrete transforms of 2-D and 3-D butterfly interconnect networks for implementing 1-D and 2-D fast Fourier transforms, respectively, which are the basic operations of intelligent optical computings.
