• Authors: Adrian Nugraha Utama, Chang Hoong Chow, Chi Huan Nguyen, Christian Kurtsiefer
• Abstract summary: We use a spatial light modulator to shape the phase of an incoming light beam to match several Laguerre-Gaussian modes of a near-concentric optical cavity. We demonstrate coupling efficiency close to the theoretical prediction for single LG modes and well-defined combinations of them, limited mainly by imperfections in the cavity alignment.

• Abstract: Optical cavities in the near-concentric regime have near-degenerate transverse modes; the tight focusing transverse modes in this regime enable strong coupling with atoms. These features provide an interesting platform to explore multi-mode interaction between atoms and light. Here, we use a spatial light modulator (SLM) to shape the phase of an incoming light beam to match several Laguerre-Gaussian (LG) modes of a near-concentric optical cavity. We demonstrate coupling efficiency close to the theoretical prediction for single LG modes and well-defined combinations of them, limited mainly by imperfections in the cavity alignment.

  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.

  Entanglement between atoms, generated by the exchange of virtual photons through a common cavity mode, grows exponentially fast. We propose to exploit this for quantum-enhanced sensing of an optical phase (common and differential between two ensembles) Our proposal can open unique opportunities for the observation of continuous variable entanglement in atomic systems and associated applications in next-generation optical atomic clocks.

The resulting Floquet polaritons involve a superposition of a set of cavity modes with a density of excitation of the atomic cloud.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
