Abstract summary: We showcase an erbium-doped whispering-gallery-mode resonator with optical modes that display intrinsic quality factors better than $108$ (linewidths less than 2 MHz) Our optical cavity sits inside a microwave resonator, allowing us to probe the spin transition which is tuned by an external magnetic field.

Abstract: We showcase an erbium-doped whispering-gallery-mode resonator with optical modes that display intrinsic quality factors better than $10^8$ (linewidths less than 2 MHz), and coupling strengths to collective erbium transitions of up to 2$\pi\times$1.2 GHz - enough to reach the ensemble strong coupling regime. Our optical cavity sits inside a microwave resonator, allowing us to probe the spin transition which is tuned by an external magnetic field. We show a modified optically detected magnetic resonance measurement that measures population transfer by a change in coupling strength rather than absorption coefficient. This modification was enabled by the strong coupling to our modes, and allows us to optically probe the spin transition detuned by more than the inhomogeneous linewidth. We contrast this measurement with electron paramagnetic resonance to experimentally show that our optical modes are confined in a region of large microwave magnetic field and we explore how such a geometry could be used for coherent microwave-optical transduction.

Sculpting ultrastrong light-matter coupling through spatial matter structuring [0.0]
We experimentally implement a novel strategy to sculpt ultrastrong multi-mode coupling. We control the number of light-matter coupled modes, their octave-spanning frequency spectra, and their response to magnetic tuning. This offers novel pathways for controlling dissipation, tailoring quantum light sources, nonlinearities, correlations, as well as entanglement in quantum information processing.

Quantum-limited millimeter wave to optical transduction [50.663540427505616]
Long distance transmission of quantum information is a central ingredient of distributed quantum information processors. Current approaches to transduction employ solid state links between electrical and optical domains. We demonstrate quantum-limited transduction of millimeter-wave (mmwave) photons into optical photons using cold $85$Rb atoms as the transducer.

Measuring the magnon-photon coupling in shaped ferromagnets: tuning of the resonance frequency [50.591267188664666]
cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures. Speed enhancement is usually achieved by optimizing the geometry of the electromagnetic cavity. We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

Raman heterodyne spectroscopy is used to probe an isotopically purified ensemble of erbium dopants. Because the erbium electron spin transition is strongly coupled to the microwave cavity, we observed Raman heterodyne signals at the resonant frequencies of the hybrid spin-cavity modes.

In this work we use an open microcavity composed of a "bottom" semiconductor distributed Bragg reflector (DBR) incorporating an n-i-p heterostructure. We demonstrate a reversible in-situ technique to tune the mode-splitting by applying uniaxial stress to the semiconductor DBR. A thorough study of the mode-splitting and its tuning across the stop-band leads to a quantitative understanding of the mechanism behind the results.
