Abstract

Cellular automata are a neighborhood logic, which transforms an array of data into a new one according to an evolution function among the neighboring cells. Cellular automata have extensive applications. Recently, optical implementations of 2-D cellular architectures become more interesting because they have the decided advantage of optical massively parallel interconnections.^1-3 However, the most suggested optical systems have large size due to the necessary free-space propagation. For practical uses, it is reasonable to develop a new packaging technique to build a compact optical system along with a simple algorithm.
