| Abstract: | By using the transfer matrix method, the transmission Spectrum and gain characteristics of symmetrical 1D ternary photonic crystals with complex permittivity defect are studied. Whether the odd or even defects are joined, the transmission peak A and transmittance peak B appear in the first and second band gap respectively. When the dielectric of the defect is complex constant and the complex is of a negative imaginary part, the transmission peak B shows a good gain. When the dielectric of the defect is complex constant and the complex has a positive imaginary part, the transmission peak A shows a certain gain characteristics, and it shows the most obvious gain characteristics for six defects. |
