Abstract

Vector beams have drawn considerable interest recently because of their unique properties in the transverse plane. Here we experimentally realize optical storage of a vector beam of light in a warm cell. The vector beam is tailored using a Sagnac interferometer containing an internal vortex phase plate, and the light pulse is stored in warm rubidium vapor. The preservation of both the spatial structure and the phase information is verified after retrieval. The implementation of vector beam storage in a room-temperature memory has potential for use in the fabrication of versatile vortex-based quantum networks.
