In order to make the direct transmission more effective, we have intended an octagonal shape cladding design in this paper. The minimum resultant effective material loss obtained from our proposed photonic crystal fiber is 0.007 cm −1 at 0.5 THz is very effective. The proposed design gives an ultra-high birefringence of 0.06 with an effective area of about 4 × 10 −6 m 2 , a core power fraction of 70% for 290 µm core diameter with a core porosity of 80% at 1.6 THz frequency and closely zero flattened dispersion of variation of 0.3 ± 0.1 ps/THz/cm at a wide frequency range of 0.7–2.1 THz.

用于太赫兹传输应用的低损耗和平坦色散八边形多孔芯 PCF

为了使直接传输更有效，我们在本文中打算采用八角形包层设计。从我们提出的光子晶体光纤获得的最小合成有效材料损耗为 0.007 cm -1 在 0.5 THz 时非常有效。所提出的设计提供了 0.06 的超高双折射，有效面积约为 4 × 10 -6 m 2 ，纤芯直​​径为 70%，纤芯直径为 70%，纤芯孔隙率在 1.6 THz 频率下为 80%。在 0.7-2.1 THz 的宽频率范围内，0.3 ± 0.1 ps/THz/cm 的零平坦色散变化。
