Additive manufacturing, micro-integration and semiconductor fabrication for compact cold atom systems — Marc Christ, •Alisa Ukhanova, Simon Kanthak, Thomas Flisgen, Conrad Zimmermann, Jörg Fricke, Olaf Brox, Andrea Knigge, Wolfgang Heinrich, and Markus Krutzik — Ferdinand-Braun-Institut (FBH), Leibniz-Institut für Höchstfrequenztechnik, Berlin

Atom-based quantum sensors allow time- and field-sensing applications with an unrivalled precision compared to their classical counterparts. While lab-based operation of cold atom-based devices is well established, a transition to mobile applications requires miniaturized subsystems with reduced complexity, high stability and low size, weight and power requirements. At FBH, we start to address the miniaturization of the sensor*s physics package towards cm-scale systems, including micro-integrated, vacuum-compatible optical systems for atom trapping and manipulation, compact, 3D-printed vacuum chambers and diffraction grating based atom sources. This poster presents an overview of our efforts towards this goal.
