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 data processing de-multiplexer components,confirmed the incident wave length 1.55μm, 1.31μm, and 1.49μm also very high transmission efficiency. In the study, we used silicon 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 de-multiplexing functions. It has the advantage of miniaturization and convenience, and effective integration of the optical signal processing components, as important components of optical communication technology.
