We introduce an all-glass, vacuum tight, fiber-integrated and alkali compatible spectroscopy device consisting of two conventional optical fibers spliced to each end of a capillary. This is mainly realized through a decentered splicing method allowing refilling of the capillary and controlling the vapor density inside. We analyze the light guidance of the setup through simulations and measurements of the transmission efficiency at different wavelengths and show that filling it with highly reactive alkali metals is possible, and that the vapor density can be controlled reliably.
我们介绍了一种全玻璃、真空密封、光纤集成且与碱兼容的光谱装置，它由两根常规光纤拼接在毛细管的两端组成。这主要通过一种偏心拼接方法实现，该方法允许对毛细管进行重新填充并控制内部的蒸汽密度。我们通过对不同波长下传输效率的模拟和测量来分析该装置的光导，并表明向其中填充高活性碱金属是可行的，且蒸汽密度能够得到可靠控制。
