“…We see that for this molecule we have a maximum ZPL fraction of 72%. This is lower than expected for DBT and could partially account for the reduction in coupling observed recently for single molecules in open-access microcavities compared to their predictions [20,24]. However, the observed fraction could also be due to the close proximity of surfaces in the nano-crystal host used in these experiments, and further tests with co-sublimation grown crystals [8] may yield a different result.…”

Phonon-Induced Optical Dephasing in Single Organic Molecules

Organic molecules have recently gained attention as novel sources of single photons. We present a joint experiment-theory analysis of the temperature-dependent emission spectra, zero-phonon linewidth, and second-order correlation function of light emitted from a single molecule. We observe spectra with a zero-phonon-line together with several additional sharp peaks, broad phonon sidebands, and a strongly temperature dependent homogeneous broadening. Our model includes both localised vibrational modes of the molecule and a thermal phonon bath, which we include non-perturbatively, and is able capture all observed features. For resonant driving we measure Rabi oscillations that become increasingly damped with temperature, which our model naturally reproduces. Our results constitute an essential characterisation of the photon coherence of these promising molecules, paving the way towards their use in future quantum information applications.

“…Polaritons are also considered for the development of treshold‐less lasers (the one‐atom laser is made possible because the atom can only emit in the cavity single mode) . Reaching the strong coupling regime for single oscillators, such as in this case with an an electronic transition at low temperature, lets us glimpse their future use for nonlinear effects; indeed, the measurement in these systems of a second‐order correlation g (2) near 0 indicates the possibility of making a single photon source from their emission. Bow‐tie plasmonic cavities also reached the strong coupling regime for a single quantum dot .…”

Strong Light–Matter Coupling as a New Tool for Molecular and Material Engineering: Quantum Approach

et al. 2018

When atoms come together and bond, these new states are called molecules and their properties determine many aspects of our daily life. Strangely enough, it is conceivable for light and molecules to bond, creating new hybrid light–matter states with far‐reaching consequences for these strongly coupled materials. Even stranger, there is no “real” light needed to obtain the effects; it simply appears from the vacuum, creating “something from nothing.” Surprisingly, the setup required to create these materials has become moderately straightforward. In its simplest form, one only needs to put a strongly absorbing material at the appropriate place between two mirrors, and quantum magic can appear. Only recently has it been discovered that strong coupling can affect a host of significant effects at a material and molecular level, which were thought to be independent of the “light” environment: phase transitions, conductivity, chemical reactions, etc. This review addresses the fundamentals of this opportunity: the quantum mechanical foundations, the relevant plasmonic and photonic structures, and a description of the various applications, connecting material chemistry with quantum information, entanglement, nonlinear optics, and chemical reactivity. Ultimately, revealing the interplay between light and matter in this new regime opens attractive avenues for various new technologies.

“…Following the initiation and improvement of the cavity samples in 2010 and 2015, Wang et al. demonstrated in 2017 the coherent coupling of a single dibenzoterrylene (DBT) molecule with an open‐access microcavity consisting of a DBR‐coated planar mirror and a metal‐coated concave mirror on silicon substrate . The cavity exhibits a moderate Q ‐factor of ≈1500 that is high enough to allow 66% enhancement of the 00ZPL at cryogen temperature and low enough to avoid the need of extra cavity stabilization.…”

Optical microcavities are powerful platforms widely applied in quantum information and integrated photonic circuits, among which the open‐access microcavity is a newly emerging cavity structure consisting of a micro‐sized concave mirror and a planar mirror controlled individually by groups of nanopositioners, whilst light emitters can be grown or transferred at the antinode of the cavity optical modes. Compared with monolithic microcavities, the open‐access microcavity enables the simultaneous realization of small mode volume, large‐range tunability, flexible structural engineering, and easiness for integration with external emitters, exhibiting extensive applications in the fields of solid‐state quantum photonics and polaritonics over the last decade. This review first introduces the basic theory and the construction methods of open‐access microcavities, followed by the recent advances of their applications in exciton‐polaritons, photon condensates, quantum light sources, and nanoparticle sensing.
