宽带隙Ge-Se基硫卤玻璃的制备及其光纤性能
|
摘要
在超低色散零点的红外硫系玻璃光纤的需求背景下,选择两组Ge-Se基的硫系玻璃组分进行对比实验研究。通过对比各组分的特性参数,优化出合适的玻璃组分,并进行光纤拉制。研究结果表明:随着碘的摩尔分数从5%增至40%,玻璃的红外透过性得到显著提高,近红外吸收的截止波长出现明显蓝移,光学带隙逐渐增大,折射率减小,色散零点波长蓝移,玻璃转变温度降低,热膨胀系数逐渐增大;通过截断法得到了2.5～11.5μm光谱范围内的光纤损耗图谱,在5.9μm处的最小光学损耗约为16.9 dB/m。
There is an active demand for infrared chalcohalide glass fiber with ultra-low zero-dispersion point. Here, two series of Ge-Se based chalcohalide glasses are selected to compare in the research. For the aim of fiber drawing, an optimized glass composition is selected after comparing the characteristics of each composition. The results show that with the increase of the molar fraction of iodine from 5% to 40%, the infrared transmittance of glasses is significantly improved, the cut-off wavelength of near-infrared absorption appears blue-shift, the optical band gap increases gradually, the refractive index decreases, and the zero-dispersion wavelength is blue-shifted. The glass transition temperature decrease and the expansion coefficient increases gradually. The fiber loss is measured by cut-back method in the spectral range of 2.5-11.5 μm, and the minimum optical loss at 5.9 μm is about 16.9 dB/m.
