Analysis of Single-Mode Propagation Characteristics of a Novel THz Wave Photonic Crystal Fiber
摘要
Abstract
A novel THz wave Photonic Crystal Fiber (THz-PCF)is designed with a low-loss material polyethylene as the sub-strate.Its single mode cutoff frequency,dispersion and loss are numerically simulated using the full-vector finite element meth-od.The results show that the frequency range of the THz single-mode propagation can be regulated by changing the cladding air hole period,air hole diameter and fiber core air hole diameter.When the cladding air hole period is 400 μm,the claddingair hole diameter is 100 μm and fiber core air hole diameter is 40 μm,the broadband single-mode propagation range can not only be increased to 0.1~5 THz ,but also the waveguide dispersion can be controlled at ±0.5 ps/(nm· km)within the frequency range of 0.5~5 THz.Moreover,the modal confinement loss will gradually decrease with the increase of the frequency and the minimum propagation loss will be 3.86 dB/m at 2.8 THz.关键词
