Abstract: Systems, devices, and techniques for performing wavelength division multiplexing or demultiplexing using one or more metamaterials in an optical communications systems are described. An optical device may be configured to shift one or more phase profiles of an optical signal using one or more stages of metamaterials to multiplex or demultiplex wavelengths of optical signals. The optical device may be an example of a stacked design with two or more stages of metamaterials stacked on top of one another. The optical device may be an example of a folded design that reflects optical signals between different stages of metamaterials.

Abstract: A quantum memory system includes a chalcogenide optical fiber link, a magnetic field generation unit and a pump laser. The chalcogenide optical fiber link includes a photon receiving end opposite a photon output end and is positioned within a magnetic field of the magnetic field generation unit when the magnetic field generation unit generates the magnetic field. The pump laser is optically coupled to the photon receiving end of the chalcogenide optical fiber link. The chalcogenide optical fiber link includes a core doped with a rare-earth element dopant. The rare-earth element dopant is configured to absorb a storage photon traversing the chalcogenide optical fiber link upon receipt of a first pump pulse output by the pump laser. Further, the rare-earth element dopant is configured to release the storage photon upon receipt of a second pump pulse output by the pump laser.
