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 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.
