Microfabricated alkali vapor cells using local sealing

International audienceWe report on a new technique to form and seal micro-fabricated cells. The technique consists in integrating single-use sealing structures actuated through laser irradiation, either to isolate cavities from each other or to connect them. Inspired by the glass-blowing techniques, we demonstrate “make-seals” and “break-seals” cells. This technique opens new
