At the beginning there was a high finesse cavity

Based on a patented technology and years of research, our technology come from a fiber-based Fabry-Perot microcavity with unrivalled properties. As a spin off the Atom Chips Group, our partnership with from Kastler Brossel Laboratory allow us to benefit from years of development on optical microcavities. Initially developed to improve quantum technologies, those fiber-based Fabry-Perot microcavities feature exceptional properties. Its laser machined-mirrors enable extremely high finesse (F>100.000), combined with microscopic waist and mode volume. Originally designed for experiments on atomic qubit detection and cavity with Bose-Einstein condensates, they have been adopted by dozens of collaborative research laboratories in quantum application and beyond.
