　　硫系玻璃光纤具有优异的中红外透光性、高的光学非线性、良好的热稳定性和化学稳定性,在中红外光传输、分子传感、非线性光学等领域备受关注.最近,我们在硫系玻璃光纤与光纤传像束的制备及应用方面取得了较显著进展.(1)制备了一系列高机械性能低损耗中红外传输硫系玻璃光纤,在激光传输和大气传感等方面得到了实际应用；(2)设计和制备了小芯径阶跃折射率硫系玻璃光纤,以其为非线性介质,采用飞秒激光抽运,获得了覆盖2-12μm、平均功率为毫瓦级的中红外超连续谱；(3)设计和制备了含～81万根直径～10 μm单丝的硫系玻璃光纤传像束,其空间分辨率达～45 lp/mm,串扰率低至～2.5％,实现了高质量的红外图像传递.

PbSe量子点玻璃与光纤的制备及其传光特性研究

半导体纳米材料(量子点)光纤,相比起掺天然稀土元素光纤,其宽带宽、高增益、低噪声等优点,为它成为一种新型的光纤材料提供了基础。由于量子点光纤放大器的带宽和增益等关键参数与量子点的掺杂浓度和尺寸分布等密切相关,因此在构成合适的量子点光纤放大器之前,对掺杂量子点玻璃的光谱特性进行研究是必要的。本文主要探讨玻璃基底PbSe量子点玻璃及光纤的制备工艺,并且对其光谱传播特性进行了研究。首先采用高温熔融法-两
