聚乙烯三角芯光子晶体光纤的太赫兹波传输研究

Investigation on terahertz wave transmission in polyethylene photonic crystal fibers with triangle core

  • 摘要: 利用全矢量有限元法,研究了一种新型三角芯聚乙烯太赫兹光子晶体光纤,对单模截止频率,色散和损耗进行了数值模拟。结果表明单模传输太赫兹频率范围可通过包层节距、包层空气孔直径和纤芯空气孔直径调节。在波长60~450 m范围内,可以获得0.1~5 THz的宽频带单模传输,波导色散值可以控制在0.5 ps/(nmkm)。在2.8 THz频率处传输损耗可以低至2.67 dB/m。

     

    Abstract: The cutoff frequency of single mode, dispersion and loss of a novel terahertz polyethylene photonic crystal fiber with triangle core were investigated by using the full-vector finite element method (FEM). The results show that the terahertz frequency range of the single-mode is tailored by the cladding pitch, cladding air hole and core air hole diameters. 0.1-5 THz broadband single-mode transmission is obtained and waveguide dispersion is limited in 0.5 ps/(nmkm) for wavelength of 60-450 m, and the transmission loss is 2.67 dB/m at 2.8 THz.
