Abstract
The simulated annealing and the guided-mode expansion methods are used to synthesize a photonic crystal slab line-defect waveguide with its guided modes of designated dispersion properties. We first synthesize a photonic crystal slab of a large photonic band gap and a designated mid-gap frequency. Based on the synthesized photonic crystal slab, a photonic crystal slab line-defect waveguide with a designated dispersion property is then synthesized. Some dispersion properties of synthesized structures are discussed and the related field distributions are illustrated to confirm the confinement of the line-defect modes. In the end of this thesis, we study the change of dispersion properties by shifting the synthesized line-defect structure, and investigate the coupling between two synthesized line-defect waveguides.
