摘要

我们展示了一种基于Tm3+掺杂氟碲酸盐玻璃纤维（TDFTFs）的114 mW s波段放大自发发射（ASE）光源。TDFTFs的芯直径为~ 8 μm， Tm3+掺杂浓度为~ 4000 ppm。通过使用~ 2.5 m长的TDFTF作为增益介质和1400/1570 nm双波长泵浦技术，在1400/1570 nm处泵浦功率为~ 1803/105 mW，实现了1440 ~ 1540 nm范围内的宽ASE。功率密度>； -20 dBm/nm时的光谱带宽为~ 84 nm (1448 ~ 1532 nm)，获得的最大输出功率约为~ 114 mW，相应的斜率效率为~ 27.5%。结果表明，TDFTFs是构建宽带s波段ASE光源的理想增益介质。

S-band amplified spontaneous emission light source based on Tm3+-doped fluorotellurite fibers

We demonstrated a 114 mW S-band amplified spontaneous emission (ASE) light source based on Tm³⁺ doped fluorotellurite glass fibers (TDFTFs). The TDFTFs had a core diameter of ∼8 μm and a Tm³⁺ doping concentration of ∼4000 ppm. By using a ∼2.5 m-long TDFTF as the gain medium and a 1400/1570 nm dual-wavelength pump technique, broad ASE ranging from 1440 to 1540 nm was achieved for the pump power of ∼1803/105 mW at 1400/1570 nm. The spectral bandwidth for power density > -20 dBm/nm was ∼84 nm (1448–1532 nm), the obtained maximum output power was about ∼114 mW, and the corresponding slope efficiency was ∼27.5 %. Our results show that TDFTFs are promising gain media for constructing broadband S-band ASE light sources.
