论文摘要
光纳米纤维引导的光可能具有从纤维表面延伸的非常陡峭的evanevancent场梯度。可以利用这来驱动附近量子发射器中的电动四极转变。在本文中，我们报告了观察$ 5S_ {1/2} $ $ \ rightarrow $ $ $ 4D_ {3/2} $ QUADRUPOLE TRUSTITION，在516.6 nm（真空中）在激光器冷却$^{87} $ RB ATOMS中仅使用几个$ unbib的umbib anan of lasib anan of lasib and anan原子云。这项工作扩展了原子理中光学纳米纤维的应用范围，以包括更多的基本测试。
Light guided by an optical nanofibre can have a very steep evanescent field gradient extending from the fibre surface. This can be exploited to drive electric quadrupole transitions in nearby quantum emitters. In this paper, we report on the observation of the $5S_{1/2}$ $\rightarrow$ $4D_{3/2}$ electric quadrupole transition at 516.6 nm (in vacuum) in laser-cooled $^{87}$Rb atoms using only a few $μ$W of laser power propagating through an optical nanofibre embedded in the atom cloud. This work extends the range of applications for optical nanofibres in atomic physics to include more fundamental tests.
