摘    要:利用传输矩阵法研究了正负折射率材料构成的异质结构光子晶体的光学传输特性。结果表明:当入射波正入射时,在这种异质结构光子晶体内出现了光子带隙,并且带隙内出现了3个极窄的透射峰,这是正负交替光子晶体和常规材料构成的同周期一维异质结构光子晶体所不具有的新颖物理特性。计算了这种异质结构光子晶体的透射谱。发现:这3个透射峰不敏感于入射角的变化,而在带隙两侧的透射峰则会随着入射角增大统一向带隙靠近;能带敏感于晶格厚度和周期数的变化。

关 键 词:光子晶体  负折射率材料  传输矩阵

Abstract:Transmission properties of photonic crystal heterostructure consisting of negative materials was stu-died by transfer matrix. The results showed that, as the incident wave at normal incidence, not only a photo-nic gap appears in this kind of photonic crystal heterostructure but also three very narrow transmission peaks appear in this gap. The positive and negative alternating one-dimensional photonic crystal and the same periods of one-dimensional heterostructure photonic crystal, which consists of conventional materials, dont have this characteristic. Transmission spectrum of this kind of photonic crystal was calculated.It was found that the three transmission peaks are insensitive to the angle of incidence, but the transmission peaks on both sides of the gap will move to the gap with the increasing of the incident angles.The energy band is sensitive to the scale length of crystal lattice and the change of the periods number.
Keywords:photonic crystal                  negative materials                  transfer matrix
