“…MEMS-induced strain has been used for this purpose, and groups have reported spectral tuning of quantum dots in a III-V material platform using electrostatic MEMS [101], [102], and in a piezoelectrically-actuated platform combining III-V quantum dots and SiN waveguides [61]. Moreover, electrostatic MEMS in III-V materials have been used to tune the mode volume in a photonic crystal cavity, which in turn tunes the Purcell enhancement, and, in the case of an embedded optical source, its emission rate [103].…”

“…Such systems, however, do not easily allow for active modulation of the emitter–environment interactions. Active and dynamic control of emitter–environment interactions has been achieved in photonic crystal cavities and nano-electromechanical systems through modulation of the effective refractive index of the environment, using electromechanical actuation 2 , mechanical oscillations 3 , 4 , or photoexcitation of free carriers 5 . These techniques, however, either only work with one fixed modulation frequency or require optical fields for fast modulation.…”

Combining the quantum optical properties of single-photon emitters with the strong near-field interactions available in nanophotonic and plasmonic systems is a powerful way of creating quantum manipulation and metrological functionalities. The ability to actively and dynamically modulate emitter-environment interactions is of particular interest in this regard. While thermal, mechanical and optical modulation have been demonstrated, electrical modulation has remained an outstanding challenge. Here we realize fast, all-electrical modulation of the near-field interactions between a nanolayer of erbium emitters and graphene, by in-situ tuning the Fermi energy of graphene. We demonstrate strong interactions with a >1000-fold increased decay rate for ~25% of the emitters, and electrically modulate these interactions with frequencies up to 300 kHz – orders of magnitude faster than the emitter’s radiative decay (~100 Hz). This constitutes an enabling platform for integrated quantum technologies, opening routes to quantum entanglement generation by collective plasmon emission or photon emission with controlled waveform.

We report the observation of coupling between a 3D microwave cavity mode and a bulk mechanical resonator mediated by piezoelectric and radiation pressure effects. The system is composed of a quartz bulk acoustic wave resonator placed inside a microwave re-entrant cavity, which is designed to act as both the electrodes for piezoelectric actuation as well as a 3D resonator. The cavity electromagnetic mode is modulated by a 5 MHz bulk acoustic wave shear mode, which is modeled and experimentally verified using the inputoutput formalism. Through finite element method simulations, we calculate the various contributions to the electromechanical coupling and discusss the potential of the system to reach high cooperativities as well as suitable applications.Nowadays, the pursuit of faster, more secure and efficient communication and information processing demands rigorous and diversified development of highly advanced technologies. To this purpose, hybrid systems have been intensely researched, as they combine the advantages of different platforms while avoiding their specific drawbacks. In particular, microwave devices figure as a rich means of photon-phonon coupling, which is a multifold platform for the investigation of fundamental science and applied physical systems. In this sense, electrostriction has been explored using piezoelectric photonic crystals to couple microwave and optical photons 1,2 , showing that piezomechanics associated to optomechanics is a promising path for the implementation of microwave to optical (MO) interconversion -a convenient route to take advantage of distinct wavelengths in order to promote the optimized information transfer required for modern communication.In this field of cavity optomechanics, device architectures have been diversified with structures such as membrane-in-the-middle cavities 3 , whispering gallery mode resonators 4,5 and photonic crystals 6 demonstrating numerous breakthrough results, such as gravitational wave detection 7 , tests of quantum gravity 5,8 , ground state cooling 9 and optomechanically induced transparency 10 .In parallel, Renning et al. 11 demonstrated valuable features of bulk acoustic wave (BAW) resonators for several quantum enabled experiments, with a study of highcoherence phonons driven by optical fields, opening new possibilities for the investigation of quantum mechanics using mesoscopic systems, precision measurements and high-fidelity information processing. BAW devices are phonon-confining structures and an acoustic analog to a a) nataliaccar@gmail.com Fabry-Perot cavity 12 , where phonons propagating in a plane are reflected at the boundary of the resonator and the external medium. Such phononic cavities are recognized by their potential to exhibit extremely high mechanical quality factors, of greater than billions at cryogenic temperatures, which is a desirable characteristic for experiments demanding large coherence times 13 .
