Abstract We have fabricated a single-mode bismuth-doped tellurite solid-core glass fiber using a multi-stage fiber fabrication method. Owing to the optimization of the glass composition and rod-in-tube fiber drawing technology, this fiber features a small mode area of 24.63 μm2 and low propagation loss of 0.9 dB/m at 1550 nm. By using the continuous-wave self-phase modulation method, the effective nonlinear parameter γ of this bismuth-doped tellurite glass fiber is estimated to be 417 W−1 km−1 at 1550 nm, which is the highest to date among all known solid-core tellurite glass fibers. Thus, we have developed an unprecedented high nonlinearity and low loss tellurite glass fiber. © 2019 Elsevier B.V. All rights reserved.

具有低传播损耗和高非线性的实芯铋-碲酸盐玻璃纤维

摘要 我们采用多级光纤制造方法制造了单模掺铋碲酸盐实芯玻璃光纤。由于玻璃成分的优化和管中棒光纤拉制技术，该光纤具有24.63 μm2的小模面积和1550 nm处0.9 dB/m的低传播损耗。通过使用连续波自相位调制方法，这种掺铋碲酸盐玻璃纤维的有效非线性参数 γ 在 1550 nm 处估计为 417 W-1 km-1，这是迄今为止所有已知固体中最高的-芯亚碲酸盐玻璃纤维。因此，我们开发了前所未有的高非线性和低损耗碲酸盐玻璃纤维。© 2019 Elsevier BV 版权所有。
