A liquid core optical fiber (LCOF) composed of hollow fiber and a solution of Eu(TTA)(3)Phen (TTA=2-thenoyltrifluoroacetone, Phen=1, 10-phenanthroline) in dimethyl sulfoxide (DMSO) has been fabricated, in which the concentration of Eu(TTA)(3)Phen in DMSO is 0.8 wt.%, the core diameter of the LCOF is 10 μm, and the fiber length is 8.1 cm. By the end pumping with a diode-pumped solid-state laser at 355 nm, a small optical signal at 613 nm was amplified with a gain of 8.2 dB at a pump power of 203 mW. Based on this experimental result, a liquid core optical fiber amplifier can be realized by the LCOF, which has wide potential applications in many optical devices.
已制备出一种由中空纤维和 Eu(TTA)(3)Phen(TTA=2- 噻吩甲酰三氟丙酮,Phen=1,10-菲咯啉)在二甲基亚砜(DMSO)中的溶液组成的液体芯光纤(LCOF),其中 DMSO 中 Eu(TTA)(3)Phen 的浓度为 0.8wt%,LCOF 的芯直径为 10μm,光纤长度为 8.1cm。通过在 355nm 处用二极管泵浦的固态激光器进行端面泵浦,在 203mW 的泵浦功率下,可将 613nm 的小光学信号放大 8.2dB,增益为 8.2dB。基于这一实验结果,通过 LCOF 可以实现液体芯光纤放大器,这在许多光学器件中具有广泛的潜在应用。
