| Abstract: | The transmission characteristics of 2D photonic crystal waveguide with dot defect are analyzed by Finite Difference Time Domain （FDTD） Method. First of all, the corresponding transmission frequency spectrum is analyzed, and then a dynamic simulation is conducted over the interactive process between light and waveguide. The results show that by introducing dot defect in the photonic crystal waveguide is helpful to control light. These may give instructions to design photonic crystals waveguide devices. |
