Abstract
A photonic Rydberg atom radio frequency receiver includes: an integrated photonic chip; an atomic vapor cell; and a receiver member including: a photonic emitter; probe light reflectors disposed on the atomic vapor cell; and coupling light reflectors disposed on the atomic vapor cell such that the pair of coupling light reflectors is optically opposed across the interior vapor space and receives and reflects the coupling laser light so that the coupling laser light is reflected between the coupling light reflectors multiple times in the interior vapor space of the atomic vapor cell.
