Physical Review A

Cooperative enhancement of channeling of emission from atoms into a nanofiber

Abstract

We show the possibility of directional guided superradiance from a linear array of distant atoms separated by one or several wavelengths in a line parallel to the axis of a nanofiber. We find that the rate and efficiency of channeling of emission from the atoms into the fiber are cooperatively enhanced by the guided modes.

Cooperative enhancement of channeling of emission from atoms into a nanofiber

Fam Le Kien, K. Hakuta

We show the possibility of directional \textit{guided} superradiance from a string of atoms separated by one or several wavelengths in a line parallel to the axis of a nanofiber. We find that the rate and efficiency of channeling of emission from the atoms into the fiber are cooperatively enhanced by the guided modes.

Collectively Enhanced Chiral Photon Emission from an Atomic Array near a Nanofiber

Ryan Jones, Giuseppe Buonaiuto, Ben Lang +2 more

Emitter ensembles interact collectively with the radiation field. In the case of a one-dimensional array of atoms near a nanofiber, this collective light-matter interaction does not only lead to an increased photon coupling to the guided modes within the fiber, but also to a drastic enhancement of the chirality in the photon emission. We show that near-perfect chirality can be achieved already for moderately sized ensembles, containing 10 to 15 atoms, by phase matching a superradiant collective guided emission mode via an external laser field. This is of importance for developing an efficient interface between atoms and waveguide structures with unidirectional coupling, with applications in quantum computing and communication such as the development of nonreciprocal photon devices or quantum information transfer channels.

Efficient channeling of cesium fluorescence into guided modes of a nanofiber

Fam Le Kien, S. Dutta Gupta, V. I. Balykin +1 more

In this work, we show that efficient channeling of atomic fluorescence into guided modes can be achieved in a realistic system of a cesium atom near a nanofiber. We find that different magnetic sublevels have different decay rates. We demonstrate that the thin fiber can indeed act as an efficient subwavelength probe, since about one fourth of the spontaneous emission from the atom can be channeled into guided modes.

Collective emission of atomic nanorings around an optical nanofiber

Juliette Jiménez Jaimes, Síle Nic Chormaic, E. Brion

We theoretically investigate the collective emission of one and two circular arrays of two-level atoms surrounding an optical nanofiber. We show that the radiation eigenmodes of a single ring selectively couple to specific guided modes of the fiber, according to their symmetry, and study how the physical parameters of the system control their nature. In particular, we identify situations in which the emission toward radiation modes is highly suppressed with respect to fiber-guided modes while the lifetime of the atomic excitation is enhanced. We further address the case of two identical nanorings positioned at a distance from each other along the nanofiber. By contrast to free-space configurations, the rings can exchange excitations even at large separation through nanofiber guided modes resulting in enhanced sub- and super-radiance with respect to the single-ring case. Our findings suggest that the ring configuration is promising for the implementation of efficient and versatile light-matter nanofiber-based interfaces and the achievement of waveguide quantum electrodynamics.
