| 摘 要： | 提出了一种纤芯与介质柱为负折射率材料、衬底为正折射率材料的新型四边形周期结构光子晶体光纤(PCF)。介绍了它的结构设计,研究了光子带隙效应导光特性。与传统四边形周期结构光子晶体光纤相比,该种光纤可以实现带隙效应导光传输,取填充比f=0.7时可获得光子带隙传输范围为880~4140nm,可应用于远红外光通信中。

| Abstract: | This paper designs a new type of photonic crystal fiber(PCF) which has negative refractive index materials in core and poles, and positive refractive index materials in underlay.The structure of this kind fiber is introduced and the band sturcture property is simulated.Compared with the traditional PCF,this new fiber can transfer signal by photonic band gap effect.When filling-fraction is 0.7,the range of wavelength by band gap effect is from 880nm to 4140nm.It will be used better in the far-infrared optical communication. |

| Keywords: | periodical quadrangle structure negative refractive index photonic crystal fiber(PCF) optical communication |
