Abstract
The first bismuth-doped superfluorescent fiber source (SFS) operating at 1.44 μm was developed. An SFS maximum output power in the double-pass backward configuration reached 82 mW with a fairly high efficiency of 31% at a pump wavelength of 1310 nm. The output spectrum is close to Gaussian shape with FWHM of ~25 nm.
摘要
研制出了首个工作于 1.44μm 的掺铋上转换超荧光光纤源（SFS）。在 1310nm 泵浦波长下，采用双程后向结构，SFS 的最大输出功率达到 82mW，效率相当高，可达 31%。输出光谱接近高斯分布，半峰全宽约为 25nm。
