The transfer matrix method is used to research the transmission spectra for one-dimensional photonic crystal of the solid dielectric constant and when containing the complex dielectric constant.The results show that the photonic quantum-well structure can be made up in both circumstances,and the position and struct of the transmission band spectra of the photonic quantum-well structure are the same.But the resonance transmission peak arises strong gain phenomenon in the circumstance that contains the negative imaginary part of the complex dielectric constant,and evident attenuating phenomenon in the circumstance that contains the positive imaginary part of the complex dielectric constant.
