基于环烯烃共聚物光子晶体光纤的太赫兹波导特性研究
|
摘要
太赫兹时域光谱技术作为一种快速发展的新型光谱分析方法在诸多领域备受关注。利用太赫兹时域光谱系统测试了太赫兹波在环烯烃共聚物光子晶体光纤传输特性。结果表明,在0. 2~0. 4 THz范围,太赫兹波被很好的约束在纤芯,损耗与衰减系数一致性良好,其传输信号强度和范围与传输距离有关。研究结果对太赫兹波导器件的研究具有一定的参考价值。
As a novel spectral analysis method,terahertz time-domain spectroscopy is rapidly developing in many fields. The transmission characteristics of terahertz in cyclic olefin copolymer photonic crystal fiber are tested by terahertz time-domain spectroscopy system. The result show that terahertz wave is well restrained in the core of optical fiber,and the loss is consistent with loss coefficient. Meanwhile,the signal strength and range of terahertz are related to the transmission distance. The research results have reference value for the research of terahertz waveguide devices.
