摘要
利用传输矩阵法研究了实介电常量和含复介电常量时一维光子晶体的透射谱.结果表明:两种情况下均构成光量子阱结构,并且光量子阱结构的透射能带谱位置和结构相同,但在含复介电常量负虚部情况下共振透射峰出现很强的增益现象,而在含复介电常量正虚部情况下共振透射峰则呈现明显的衰减现象.
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.
