Beams with polarization singularities have attracted immense recent attention in a wide array of scientific and technological disciplines. We demonstrate a class of optical fibers in which these beams can be generated and propagated over long lengths with unprecedented stability, even in the presence of strong bend perturbations. This opens the door to exploiting nonlinear fiber optics to manipulate such beams. This fiber also possesses the intriguingly counterintuitive property of being polarization maintaining despite being strictly cylindrically symmetric, a prospect hitherto considered infeasible with optical fibers.
具有偏振奇点的光束在广泛的科学和技术学科中引起了极大的关注。我们展示了一类光纤，在这些光纤中，即使在存在强弯曲扰动的情况下，这些光束也可以以前所未有的稳定性产生和传播。这为利用非线性光纤光学来操纵这些光束开辟了道路。这种光纤还具有一个有趣的违反直觉的特性，即尽管严格地具有圆柱对称性，但它仍然保持偏振，这是以前认为光纤无法实现的前景。
