| Abstract: | A finite difference in time domain(FDTD)method is employed to calculate single defect modes and multiple defect modes for E-polarization in a two-dimensional photonic crystal consisting of anisotropic cylinders of tellurium.It is shown that the defect modes resonant frequency inside the complete band gap varies as the radius changes,which can be explained qualitatively in theory. |
