| 摘 要： | 将具有高本征吸收的极化材料SiC引入到一维光子晶体中间,形成一维光子晶体微腔。利用传输矩阵方法,研究了这种含SiC材料的一维光子晶体微腔的光学特性:包括透射率、反射率和吸收率。研究结果表明该结构在波长λ=12.6μm处存在一个全吸收峰,该吸收峰在0°～50°的入射角度范围内不随角度和偏振模式的影响。该结构可以用来制作宽角度窄带全吸收器件,有望在热发射、太阳能光伏电池中得到应用。

| Abstract: | By introducing the polar material with high absorption into one dimensional photonic crystal, we construct one dimensional photonic crystal microcavity. With the help of transfer matrix methods, the transmission、reflection and absorption properties of one dimensional photonic crystal containing SiC microcavity are studied. The results show that the structure has a total absorption peak at the wavelength λ=12.6 μm, that the absorption peak is insensitive to incident angle and polarization between 0 to 50 degrees. The structure can be used to fabricate total absorber with wide angle and may find potential application in thermal emission and photovoltaic cells. |
