【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%。更多还原

【Abstract】 A wide-band infrared optical fiber is fabricated by liquid-phase chemistry method.The property of silver and silver iodideplate and their spectrum characters are analyzed.Experimental results show that:by controlling the time and temperature of iodination,the smoothness of the plate and the transmission efficiency can be improved.Wide-band infrared optical fiber with transmission band from 3 m to 12 m and transmission efficiency as high as 70% at 10.6 m can be realized.更多还原
