Development of micro-integrated optical systems for compact atom-based quantum sensors — •Conrad Zimmermann, Marc Christ, Alisa Ukhanova, and Markus Krutzik — Ferdinand-Braun-Institut (FBH), Berlin, Germany

The miniaturization of atom-based quantum sensor experiments towards robust and compact quantum sensor devices holds great potential to improve a variety of applications, such as timekeeping, navigation and high-sensitivity field sensing. Working on the physics packages, we develop and qualify necessary integration technologies to realize miniaturized, ultra-stable optical systems to generate, manipulate and detect atomic quantum gases. For further functionalization, active optical components are investigated. We report on our technology toolbox and the latest qualification efforts regarding the micro-integration of free-space optical systems using adhesive bonding processes.

Towards higher grades of system integration, one approach is to integrate optical subsystems within the ultra-high vacuum (UHV) system, requiring ultra-low outgassing properties of all bonds and components. Furthermore, additive manufacturing of ceramics and metals is utilized, e.g. to realize compact and functionalized vacuum systems.

This work is supported by the German Space Agency (DLR) with funds provided by the Federal Ministry for Economic Affairs and Climate Action (BMWK) due to an enactment of the German Bundestag under grant numbers DLR50WM1949, 50RK1978, 50WM2070 and 50WM2268.
