Abstract

We propose a solid-state platform for quantum sensing applications based on collective emission effects from silicon-vacancy (SiV) centers implanted in ordered subwavelength arrays, supported by numerical simulations, fabrication, and preliminary characterization.

Collective emission of subwavelengths atom-like emitter arrays in the presence of inhomogeneous broadening

Uri Israeli, Shahar Levi, Sagi Ben-Avi +4 more

Quantum metasurfaces comprised of subwavelength atomic arrays emerged as a promising platform for enhanced atom-photon interaction. However, realizing such a system with solid-state emitters has been considered impractical due to strong inhomogeneous broadening, which was expected to suppress the photon-mediated interactions that underpin collective emission. Here we report the observation of collective emission from subwavelength arrays of silicon-vacancy centres in diamond -- solid-state emitters whose inhomogeneous broadening exceeds the natural linewidth by two orders of magnitude -- demonstrating that collective effects such as resonance shifts, modified decay rates and directional coherent emission survive this disorder. A crucial enabling element is the implantation of a high density of silicon ions at each array site. This creates so-called superatoms, local ensembles that probabilistically achieve frequency matching across the array and enhance the collective response. We support our observations with a theoretical analysis explaining the mechanisms that preserve the collective effects even in the presence of inhomogeneity. These observations have direct implications for the realization of subwavelength arrays in any solid-state system, paving the way for quantum-emitter metasurfaces that are naturally integrated into nanophotonic environments.

Coupling Quantum Emitters in Nanodiamonds to Microring Resonators for Integrated Quantum Photonics

Victor Leong, Dmitry A. Kalashnikov, Jibo Dai +5 more

Quantum photonics platforms hold considerable potential for the rapid development and deployment of quantum information and computing technologies. Color centers in diamond, such as silicon-vacancy (SiV) centers, have numerous attractive properties for such applications, including high brightness, narrow zero-phonon line (ZPL) linewidths at 737nm, and stable single-photon emission insusceptible to electric field fluctuations [1]. Color centers in photonic diamond nanostructures have been demonstrated recently [2], but their fabrication is challenging and requires sophisticated techniques and equipment.
