“…In addition to the fundamental aspects related to the phenomena of Fano resonance, the interaction of a plasmonic system with atomic vapour such as Rb is very appealing due to the myriad applications that have been demonstrated using alkali vapours in the past decades [42][43][44][45] . Indeed, the community has vast experience in manipulating and controlling such vapours close to room temperature, using both linear and nonlinear interrogation techniques.…”

Fano resonances and all-optical switching in a resonantly coupled plasmonic–atomic system

The possibility of combining atomic and plasmonic resonances opens new avenues for tailoring the spectral properties of materials. Following the rapid progress in the field of plasmonics, it is now possible to confine light to unprecedented nanometre dimensions, enhancing light-matter interactions at the nanoscale. However, the resonant coupling between the relatively broad plasmonic resonance and the ultra-narrow fundamental atomic line remains challenging. Here we demonstrate a resonantly coupled plasmonic-atomic platform consisting of a surface plasmon resonance and rubidium ( 85 Rb) atomic vapour. Taking advantage of the Fano interplay between the atomic and plasmonic resonances, we are able to control the lineshape and the dispersion of this hybrid system. Furthermore, by exploiting the plasmonic enhancement of light-matter interactions, we demonstrate alloptical control of the Fano resonance by introducing an additional pump beam.

“…The enhanced sensitivity provided by the plasmonic resonance can also be used for metrology applications, for example, magnetometers 44 , frequency standards 45 and encoders. For instance, it has been recently demonstrated that using evanescent wavelengths and 100-mm coated cells, one can measure magnetic fields in the pT level 47 .…”

Additive manufacturing (AM) of passive microwave components is of high interest for the costeffective and rapid prototyping or manufacture of devices with complex geometries. Here, we present an experimental study on the properties of recently demonstrated microwave resonator cavities manufactured by AM, in view of their applications to high-performance compact atomic clocks. The microwave cavities employ a loop-gap geometry using six electrodes. The critical electrode structures were manufactured monolithically using two different approaches: Stereolithography (SLA) of a polymer followed by metal coating and Selective Laser Melting (SLM) of aluminum. The tested microwave cavities show the desired TE 011 -like resonant mode at the Rb clock frequency of %6.835 GHz, with a microwave magnetic field highly parallel to the quantization axis across the vapor cell. When operated in an atomic clock setup, the measured atomic Rabi oscillations are comparable to those observed for conventionally manufactured cavities and indicate a good uniformity of the field amplitude across the vapor cell. Employing a time-domain Ramsey scheme on one of the SLA cavities, high-contrast (34%) Ramsey fringes are observed for the Rb clock transition, along with a narrow (166 Hz linewidth) central fringe. The measured clock stability of 2.2 Â 10 À13 s À1/2 up to the integration time of 30 s is comparable to the current state-of-the-art stabilities of compact vapor-cell clocks based on conventional microwave cavities and thus demonstrates the feasibil-ity of the approach.Compact microwave atomic clocks 1 based on alkali vapor cells 2,3 are widely employed as stable frequency references in numerous applications, ranging from telecommunication networks 4 to onboard clocks in satellite navigation systems. 5,6 In such atomic clocks, the frequency of a quartz local oscillator is stabilized to an inherently stable microwave transition in an alkali atom vapor held in a vapor cell. This greatly suppresses the quartz's fractional frequency instabilities to the 10 À12 to <10 À14 range (timing accuracies of 0.1 ls to <1 ns, respectively) over timescales up to one day. During the last decade, thanks to the employment of laser optical pumping, important advances were made in vapor-cell Rb atomic clocks based on the double-resonance (DR) scheme, using both the continuouswave (CW) 7 and the pulsed optical pumping (POP) interrogation (Ramsey scheme), 8,9 where the pulsed Ramsey scheme is of particular interest for highly compact and high-performance Rb cell clocks. In all types of DR atomic clocks, the microwave resonator cavity is a critical component for applying the microwave field to the atoms in a well-controlled geometry. In view of practical applications, this microwave cavity should be small and light-weight and feature simple and fast assembly. In DR atomic clocks, such cavities are generally manufactured by conventional subtractive precision machining of metals, often followed by time-consuming assembly steps requiring precise positioning or ali...

“…Significant recent progress in optical spectroscopy and measurement techniques has led to the achievement of relative standard uncertainties in optical frequency standards that are comparable to the Cs microwave benchmark. In 2006, the International Committee for Weights and Measures (CIPM) recommended that the following transitions frequencies be used as secondary representations of the second [5]: ground-state hyperfine microwave transition in 87 Rb [6], [7], 5s 2 S 1/2 − 4d 2 D 5/2 optical transition of the 88 Sr + ion [8], [9], 5d 10 6s 2 S 1/2 (F = 0) − 5d 9 6s 2 2 D 5/2 (F = 2) optical transition in 199 Hg + ion [10], [11], 6s 2 S 1/2 (F = 0) − 5d 2 D 5/2 (F = 2) optical transition in 171 Yb + ion [12], [13] and 5s 2 1 S 0 − 5s5p 3 P 0 transition in 87 Sr neutral atom [14], 1 Email: msafrono@udel.edu [15], [16]. With better stability and accuracy, as well as extremely low systematic perturbations, such optical frequency standards can reach a systematic fractional uncertainty of order 10 −18 [9], [17].…”

Abstract-A review of theoretical calculations of black-body radiation (BBR) shifts in various systems of interest to atomic clock research in presented. Calculations for monovalent systems, such as Ca + , Sr + , and Rb are carried out using a relativistic all-order single-double method, where all single and double excitations of the Dirac-Fock wave function are included to all orders of perturbation theory. A recently developed method for accurate calculations of BBR shifts in divalent atoms such as Sr is discussed. This approach combines the relativistic all-order method and the configuration interaction method. The evaluation of uncertainties in theoretical values of BBR shifts is discussed in detail.
