设计一种三硫化二砷混合玻璃光纤( As2 S3-silica hybrid glass fiber, As2 S3-silica HGF),通过调整纤芯直径大小,在1000~6000 nm波长范围内对其色散特性进行仿真分析.结果表明,当纤芯直径为1．2μm时,光纤有两个零色散波长( zero dispersion wavelength, ZDW),分别是1450和2870 nm,反常色散区覆盖1450~2870 nm.用2μm激光器泵浦光纤,通过改变泵浦激光的峰值功率和脉冲半极大宽度(full width at half maximum, FWHM),模拟分析了中红外超连续谱(mid-infrared supercontinuum, mid-IR SC)产生的特性.

A new As2 S3-silica hybrid grass fiber was designed. The corresponding dispersion properties were realized by adjusting the fiber core diameter in the wavelength range from 1 000 nm to 6 000 nm. The simulation results have shown that two zero dispersion wavelengths could be achieved with a core diameter of 1. 2 μm and the anomalous dispersion in this fiber design was from 1 450 nm to 2 870 nm. The characteristics of mid-infrared supercontinuum generation from this As2 S3-silica hybrid grass fiber are analyzed by changing the pump pulse parameters, i. e. peak pump power and the full width at half maximum of the pulse at 2 μm wavelength.
