碩士 === 中華科技大學 === 機電光工程研究所碩士班 === 100 === In the past 20 years, photonic crystal periodic dielectric materials, with interesting and unusual magnetic properties, applications in various fields has been remarkable. This paper is the Plane Wave Expansion method (PWE) and Finite-Difference Time Domain (FDTD) simulation of photonic crystal structures, and by its characteristic design a Optical logic gates components ,confirmed the incident wave length 1.55μ m also very high transmission efficiency. In the study, we used OG Macromolecule dielectric material for the column in the two-dimensional plane photonic crystal structure. To adjust the middle of interference and the coupling region so that light effectively confined to the structure, with achieve sub-wave – de-multiplexing functions. It has the advantage of miniaturization and convenience, and effective integration of the Optical logic gates, as important components of optical communication technology.
