低损耗、低色散、高双折射太赫兹多孔光纤
Low loss, low dispersion and highly birefringent terahertz porous fibers
摘要：
我们证明了多孔光纤在扩展的频率范围内具有低的有效材料损耗，比亚波长实芯光纤可实现的带宽大4.5倍。我们还表明，这些新的光纤可以被设计为具有接近零的色散为0.5-1太赫兹导致整体太赫兹信号退化。此外，它表明，使用不对称的亚波长空气孔内的核心导致高双折射~0.026。这为在太赫兹波段实现新型保偏光纤开辟了可能。
英文摘要：
We demonstrate that porous fibers have low effective material loss over an extended frequency range, 4.5 times larger bandwidth than that can be achieved in sub-wavelength solid core fibers. We also show that these new fibers can be designed to have near zero dispersion for 0.5-1 THz resulting to overall less terahertz signal degradation. In addition, it is demonstrated that the use of asymmetrical sub-wavelength air-holes within the core leads to high birefringence ~0.026. This opens up the potential for realization of novel polarization preserving fibers in the terahertz regime.
