Spectral engineering of cavity-protected polaritons in an atomic ensemble
Our paper presenting the demonstration of spectral engineering of polaritons in a cold atom cavity system has been published in Nature Physics on May 2nd, 2023. You can read the full paper by accessing it here: https://rdcu.be/dbmX7
In this study, we investigate the influence of strong cavity interactions on the protection of polartions against emitter inhomogeneities, hightlighting the role played by dark states in this system. Leveraging the cavity protection effect, we successfully engineer the spectrum of polaritons, resulting in the generation of polartions with muliple frequencies. This can lead to applications in quantum networks, particularly for shaping single-photon emission.

MiTra receives ERC PoC grant
Our miniature greenhouse gas analyzer project has been awarded an ERC Proof-of-Concept (PoC) grant. This will boost our development of an ultracompact yet very accurate analyzer based on our fiber Fabry-Perot microcavity technology. It will measure the concentration of greenhouse gases with an accuracy and stability rivaling state-of-the art instruments, but in a handheld, drone-mountable form factor – less then one tenth the weight and one hundreth the volume of existing instruments.
