Experimental demonstration of a cooled silica fiber amplifier

Jennifer M. Knall, Magnus Engholm, Tommy Boilard +2 more

We will report the first demonstration of an optically cooled fiber amplifier. The fiber was made of silica, had a core doped with Yb, and was core-pumped to achieve both gain and cooling in the core via anti-Stokes fluorescence. Gains larger than 10 dB were measured while maintaining a negative average temperature change along the fiber.

Non-Reciprocal Amplification of Light Using Cold Atoms Coupled to an Optical Nanofiber

Sebastian Pucher, Christian Liedl, Shu‐Wei Jin +2 more

Optical nanofibers realized as the waist of tapered silica fibers can be used to trap and optically interface laser-cooled atoms. Building on this system, we experimentally show a novel scheme for the nonreciprocal Raman amplification of light. While typically either the magneto-optical effect, a temporal modulation or an optical nonlinearity is employed to break reciprocity, in our approach, this results from the spin of the atoms forming the gain medium. By taking advantage of the inherent spin-momentum locking present in optical nanofibers, we perform an experiment in which we set the amplification direction by a suitable preparation of the atomic spin state. Our approach is general and, suitable quantum emitters provided, could also be implemented beyond the optical domain of the electromagnetic spectrum.Optical nanofibers realized as the waist of tapered silica fibers can be used to trap and optically interface laser-cooled atoms.

Measurement of nonreciprocal stimulated Raman scattering in silicon photonic wires

Michael M. Krause, Jost Müller, E. Brinkmeyer

Nonreciprocal stimulated Raman scattering in a silicon waveguide is shown experimentally for the first time: the measured backward-to-forward transmission ratio is enhanced when a probe laser is tuned to the Stokes wavelength.
