一维光子晶体Si/C60多层膜的透射性质

用传输矩阵法推导了一维光子晶体的透射率公式,研究了[Si(30 nm)/C60(70 nm)N体系当电磁波沿z方向入射时不同周期层数的透射特性.结果表明,当周期数达16时在325～585 nm波段内的透射率基本为零且电磁波损耗最低仅为1％；而在585～825 nm波段存在多个完全透射峰,其半峰宽随波长增加而增加.改变掠...

Transmission Characteristics of 1D Photonic Crystals Using Si/C_(60) Multilayer

The transmission coefficient formula of one-dimensional photonic crystal was derived by using transfer matrix method(TMM).The transmission characteristic on the different periodic layers of the system built up with [Si(30 nm)/C60(70 nm)]N was studied when the electromagnetic wave incidents along the z direction.The results show that when N is 16,the transmission rate of the wave band of 325～585 nm is almost zero and the electromagnetic wave lost can be reduced to 1%.In the wave band of 585～825 nm number of complete transmission peaks appear,whose half-peak width increases with the wavelength.There is different effect to the transmission rate on TE and TM polarization mode when the incident angles change.The structure can be used for some new photonic devices with its double transmission properties in the visible light.
