碩士 === 中華技術學院 === 機電光工程研究所碩士班 === 97 === In this paper, cloth made to shorten the grid reflection of electromagnetic wave propagation and principles, with numerical analysis and simulation software, designed to look forward to the best of the photonic crystal structure parameters, and photonic crystal waveguide to design digital logic and two-way optical WDM Optical components, etc., and this is a low-consumption and structure of the small advantages. Silicon material to study for the dielectric cylinder, with Prague Fanshedinglv (Bragg's law) and finite difference time-domain (Finite-Difference Time-Domain), such as numerical analysis, to design cycles and a radius of lattice parameters, create Nano with the structure of photonic crystals (Photonic Crystal), and materials with different refractive index of energy gap (Bandgap) to form waveguide, analog design logic gates and optical-wave two-way optical components such as multiplexers, confirmed the incident wave length 1.55μ m and 1.31 μ m also very high transmission efficiency.
