Nanofiber-segment ring resonator

Abstract

We describe a fiber ring resonator comprised of a relatively long loop of standard single-mode fiber with a short nanofiber segment. The evanescent mode of the nanofiber segment allows the cavity-enhanced field to interact with atoms in close proximity to the nanofiber surface. We report on an experiment using a warm atomic vapor and low-finesse cavity, and briefly discuss the potential for reaching the strong coupling regime of cavity QED by using trapped atoms and a high-finesse cavity of this kind.

Optical nanofiber-based cavity induced by periodic air-nanohole arrays

“…8,9,28 In addition, a fiber ring cavity containing a nanofiber section that strongly couples atoms to the cavity mode has been studied recently. 29,30 In this letter, we investigate a nanofiber-based cavity that incorporates both FBG and PhC structures in order to exploit the advantages of both simultaneously. Mirrors in this cavity exhibit higher reflectivity than other reported nanofiber cavities that are based solely on Bragg gratings or on 1-D photonic crystal structures.…”

Transmission characteristics of optical nanofibers in metastable xenon

“…In contrast, for applications requiring the highest possible long-term ONF transmission, but where the highest OD's are not critical, the use of Xe* may be beneficial. This latter class of applications may include, for example, experiments using various types of nanofiber-based optical resonators [27][28][29][30].…”
