Light guided by an optical nanofibre has a very steep evanescent field gradient extending from the fibre surface. This gradient can be exploited to drive electric quadrupole transitions in nearby quantum emitters. In this paper, we report on the obse

A simple, narrow, and robust atomic frequency reference at 993 nm exploiting the rubidium (Rb) $5\mathit{S}_{1/2}$ to $6\mathit{S}_{1/2}$ transition using one-color two-photon excitation

We experimentally demonstrate a one-color two-photon transition from the $5\mathit{S}_{1/2}$ ground state to the $6\mathit{S}_{1/2}$ excited state in rubidium (Rb) vapor using a continuous wave laser at 993 nm. The Rb vapor contains both isotopes ($^

Publikováno v: CLEO Pacific Rim Conference.

We present recent work on the integration of ultrathin optical fibers into a cold 87Rb system, for exploring multiphoton processes and the generation of Rydberg atoms near a dielectric surface. Fabrication of structured ultrathin fibers will also be

Publikováno v: 2016 Progress in Electromagnetic Research Symposium (PIERS).

Optical nanofibres (ONF), which are fabricated by tapering standard optical fibre over a heat source to subwavelength diameter [1], have recently come to the fore as ideal tools for atom-photon hybrid quantum systems. For a recent review on the topic
