Situation
The project addresses current limitations in size, reliability, manufacturing, and long-term stability of laser-stabilized quantum sensors such as atomic clocks and magnetometers. It brings together three Swiss partners: CSEM, contributing expertise in MEMS atomic vapor cells and quantum sensor integration; FEMTOprint, providing advanced 3D laser glass microfabrication for monolithic optical enclosures; and BFH, offering under-vacuum laser processing expertise. Together, they will demonstrate a sugar-sized, all-glass, vacuum-packaged laser stabilization system based on saturated absorption, delivering state-of-the-art accuracy, long lifetime, and scalable manufacturing. This technology will enable next-generation quantum sensors and improved laser stability for chip-scale atomic clocks and high-capacity telecommunications.
