IPAS Photon-Photon Interactions research featured in Physical Review Applied

Chris Perella.Strong photon-photon interactions are a key requirement for numerous quantum communication and computation protocols. Generation of photon-photon interactions mediated by atomic vapours in hollow waveguides has shown great promise, with their efficiencies enhanced by the tight transverse confinement and extended interaction length. We demonstrate, both experimentally and theoretically, the strength of such interactions inside a series of hollow-core photonic crystal fibres and show they only scale with the optical mode diameter, not mode area as might be initially expected, a result of atomic motion within the waveguides. This insight will allow waveguides to be designed to target specific photon-photon interaction strengths.
