A team of scientists from the Ludwig Maximilian University of Munich and attocube systems AG have engineered a Fabry-Pérot cavity at cryogenic temperatures under closed-cycle cooling conditions. The results have been published in PRX Quantum.
Studying the interactions between light and matter is fundamental for new developments in science and technology. Related experiments in solid state physics use devices called optical resonators to confine light to a small volume in space for a prolonged period of time. One method of creating an optical resonator is to position two mirrors facing each other at a close distance, calculated based on the optical wavelength, confining the light between the parallel surfaces.
