“…In Fig. 8 we compare atom-cavity systems prepared by experimenters for the strong coupling regime over the past decades with respect to their g∕ and ∕ -values for both bulk cavity experiments [51][52][53] and FFPCs [42][43][44][45][46][47][48][49][50]. Selected sets of parameters for the ( g, , )-values used in different laboratories show a clear tendency to take advantage of FFPC properties especially in the fast cavity regime, i.e.…”

“…The high spectral selectivity of FFPCs allows to also control the emission properties of molecules for selected transitions out of complex structure and at the single emitter level [65]. The enhancement of molecule-light field interaction in a FFPC based microcavity has been shown to realize nonlinear wave mixing processes at the single-photon level [45,66].…”

Achievements and perspectives of optical fiber Fabry–Perot cavities

Fabry–Perot interferometers have stimulated numerous scientific and technical applications ranging from high-resolution spectroscopy over metrology, optical filters, to interfaces of light and matter at the quantum limit and more. End facet machining of optical fibers has enabled the miniaturization of optical Fabry–Perot cavities. Integration with fiber wave guide technology allows for small yet open devices with favorable scaling properties including mechanical stability and compact mode geometry. These fiber Fabry–Perot cavities (FFPCs) are stimulating extended applications in many fields including cavity quantum electrodynamics, optomechanics, sensing, nonlinear optics and more. Here we summarize the state of the art of devices based on FFPCs, provide an overview of applications and conclude with expected further research activities.

“…8. A non-exhaustive survey of normalized parameter sets {g, κ, γ} and C = g 2 /2κγ used in cavity QED experiments with fiber based Fabry-Perot resonators (FFPCs sorted from left to right: [37][38][39][40][41][42][43][44][45]) with respect to performance in atom field coupling strength g/γ vs. resonator field fiber coupling rate κ/γ. For comparison a small set of bulk cavity system parameters is shown, too, from [46][47][48] sorted from top to bottom.…”

“…and applications (physical chemistry, physics, biology, materials science, etc) 7,8 . One of the elegant consequences of single-molecule science has been the emergence of molecular quantum optics, which has reached the same level of sophistication that is known from experiments on gaseous atoms, GaAs-based quantum dots, or color centers in diamond over the past two decades [9][10][11][12][13][14] . These studies take place at liquid helium temperature, where the zerophonon line (ZPL) transition reaches its Fourier limit in the order of 10-50 MHz.…”

Vibrational levels of the electronic ground states in dye molecules have not been previously explored at high resolution in solid matrices. We present new spectroscopic measurements on single polycyclic aromatic molecules of dibenzoterrylene embedded in an organic crystal made of para-dichlorobenzene. To do this, we use narrow-band continuous-wave lasers and combine spectroscopy methods based on fluorescence excitation and stimulated emission depletion (STED) to select individual vibronic transitions at a resolution of ∼ 30 MHz dictated by the linewidth of the electronic excited state. In this fashion, we identify several exceptionally narrow vibronic levels in the electronic ground state with linewidths down to values around 2 GHz. Additionally, we sample the distribution of vibronic wavenumbers, relaxation rates, and Franck-Condon factors, both in the electronic ground and excited states for a handful of individual molecules. We discuss various noteworthy experimental findings and compare them with the outcome of DFT calculations. The highly detailed vibronic spectra obtained in our work pave the way for studying the nanoscopic local environment of single molecules. The approach also provides an improved understanding of the vibrational relaxation mechanisms in the electronic ground state, which may help to create long-lived vibrational states for applications in quantum technology.
