Abstract
A low-cost, mass-producible laser-cooling platform would have a transformative effect in the burgeoning field of quantum technologies and the wider research of atomic sensors. Recent advancements in the micro-fabrication of diffractive optics and vacuum apparatus have paved the way for a simple, stackable solution to the laser cooling of alkali atoms. In this paper we will highlight our recent investigations into a chip-scale, cold-atom platform, outlining our approach for on-chip wavelength referencing, examining a solution for imaging atoms in a planar stacked device, and finally discussing the limitations to passively pumped vacuum longevity. These results will be discussed in the context of an outlined road-map for the production and commercialisation of chip-scale, cold-atom sensors.
