Integration of Germanium-Vacancy Single-Photon Emitter Arrays in Diamond Nanopillars

Researchers have successfully fabricated and characterized germanium-vacancy (GeV) color center arrays in diamond, a crucial step toward the development of integrated photonic chips. Using focused ion beam (FIB) implantation with Ge²⁺ ions at nanometer precision, they created emitter arrays aligned to 300 nm nanopillar waveguides, enhancing photon collection efficiency and signal-to-background ratio by a factor of 8. Importantly, the photophysical properties of the GeV centers remained unaltered, demonstrating the robustness of this approach.

This work, led by Jacopo Forneris, highlights the Quantum Foundry’s expertise in nanopatterning materials with color centers beyond NVs, paving the way for new applications in quantum photonics.
