Abstract A novel kind of near-infrared communication window of photonic crystal fiber (PCF) polarization filter based on filled silver nanowire is proposed in this paper. The silver nanowire is selectively filled in a air hole of the cladding, and the performance of this PCF is analyzed by changing the diameter d2 of the near-core small air holes by finite element method (FEM). It is found that the confinement loss of x-polarization is 10738.726 dB/m, and that of y-polarization is 272.2325 dB/m at the resonance wavelength of 1.24 μm when the diameter d2 = 0.3 μm. Furthermore, when the fiber length is 1 mm, the crosstalks of x and y-polarization are −90.9 dB and 85 dB at the resonance wavelength of 1.24 μm and 1.32 μm, respectively. Thus, it can well realize the function of polarization filtering in two communication bands.

基于填充银纳米线的部分纤芯高双折射光子晶体光纤的表面等离子体增强偏振滤光片

摘要 本文提出了一种新型的基于填充银纳米线的光子晶体光纤(PCF)偏振滤光片近红外通信窗口。将银纳米线选择性地填充在包层的气孔中,并通过有限元法(FEM)改变近纤芯小气孔的直径d2来分析该PCF的性能。发现当直径d2 = 0.3 μm时,在谐振波长1.24 μm处,x偏振的约束损耗为10738.726 dB/m,y偏振的约束损耗为272.2325 dB/m。此外,当光纤长度为 1 mm 时,x 和 y 偏振的串扰在 1.24 μm 和 1.32 μm 的谐振波长下分别为 -90.9 dB 和 85 dB。因此,它可以很好地实现两个通信频段的偏振滤波功能。
