碩士 === 國立交通大學 === 光電工程系所 === 93 === In this thesis, defect modes of two-dimensional photonic crystal nano-cavity are analyzed. The defect is formed by removing a single air hole from array of air holes of hexagonal lattice arrangement on a dielectric slab. First, the finite difference time domain method with various boundary conditions is introduced. Second, symmetry analysis of defect modes and design rules for high quality factor cavities are presented. Finally, techniques of the simulation and the results of the simulation, like photonic band structures, resonant frequencies, mode profiles, and quality factors are exhibited.
