提出并分析了利用蜘蛛网结构包层空芯布喇格光纤在0.65μm～1.55μm和200μm～500μm波长范围得到低损耗传输的可能性.采用渐近转移矩阵公式所做的分析结果表明:这种光纤的传输损耗远低于构成光纤所用塑料的吸收损耗.在0.65μm～1.54μm的可见至近红外波段,这种光纤结构可把构成光纤所用塑料的吸收损耗抑制为1/237000,甚至可抑制为1/1300000;在200μm～500μm的太赫兹波段,这种光纤结构可把构成光纤所用塑料的吸收损耗抑制为1/8962,甚至可抑制为1/83390.因此用便宜的塑料,可以在可见至太赫兹波段用这种光纤构成较长距离、较高带宽的光纤通信系统,并实现波分复用(WDM).
The possibility of low loss transmission in the range of 0.65μm ~ 1.55μm and 200μm ~ 500μm using the hollow fiber Bragg fiber with cobweb structure was proposed and analyzed.The results of the analysis using the asymptotic transfer matrix formula show that The transmission loss of the optical fiber is much lower than the absorption loss of the plastic used for forming the optical fiber. This optical fiber structure suppresses the absorption loss of the plastic material constituting the optical fiber to 1/237000 in the visible to near infrared range of 0.65 m to 1.54 m, Is 1/1300000, and in the terahertz band of 200 μm to 500 μm, this optical fiber structure can suppress the absorption loss of the plastic material constituting the optical fiber to 1/8962 and even to 1/83390, so that it can be seen with cheap plastic This terahertz band uses this type of optical fiber to form longer distance, higher bandwidth optical fiber communication systems and to achieve wavelength division multiplexing (WDM).
