摘要
提出并分析了利用蜘蛛网结构包层空芯布喇格光纤在0.65 μm~1.55 μm和200 μm~500 μm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0.65 μm~1.54 μm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1/237 000,甚至可抑制为1/1 300 000;在200 μm~500 μm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1/8 962,甚至可抑制为1/83 390.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).
Abstract
The possibility of using a hollow-core Bragg fiber with cobweb- structured cladding to obtain low-loss transmission in wavelength range 0.65 μm~ 1.55 μm and 200 μm~ 500 μm is proposed and analyzed. The results show that the transmission losses of the hollow-core Bragg fibers with cobweb cladding are far less than the absorption losses of constituent plastics. Thus, using inexpensive plastics, it allows the fibers to meet the needs of transmission longer-distance and higher-bandwidth and to realize the wavelength division multiplexing(WDM).
