摘　　要：利用液相化学沉积法,研制出了一种宽波段的红外特种光纤,并对该光纤的膜层结构和光谱特性进行了实验分析。研究结果表明:通过控制碘化时间和碘化温度,可以提到光纤膜层的光滑度,增大光纤的透过率。实验制备的红外传能光纤实现了3～12m的宽带传输,且在10.6m处透过率高达70%。A wide-band infrared optical fiber is fabricated by liquid-phase chemistry method. The property of silver and silver iodide-plate and their spectrum characters are analyzed. Experimental results show that： by controlling the time and temperature ofiodination, the smoothness of the plate and the transmission efficiency can be improved. Wide-band infrared optical fiber with transmission band from 3 μm to 12 μm and transmission efficiency as high as 70% at 10.6 μm can be realized.
