Abstract

Optical microcavities and waveguides coupled to diamond are needed to enable efficient communication between quantum systems such as nitrogen-vacancy centers which are known already to have long electron spin coherence lifetimes. This paper describes recent progress in realizing microcavities with low loss and small mode volume in two hybrid systems: silica microdisks coupled to diamond nanoparticles, and gallium phosphide microdisks coupled to single-crystal diamond. A theoretical proposal for a gallium phosphide nanowire photonic crystal cavity coupled to diamond is also discussed. Comparing the two material systems, silica microdisks are easier to fabricate and test. However, at low temperature, nitrogen-vacancy centers in bulk diamond are spectrally more stable, and we expect that in the long term the bulk diamond approach will be better suited for on-chip integration of a photonic network.

  • Progress in diamond quantum photonics has been enabled by advances in CVD growth of single crystal diamond with required purity and low defect density, and by advances in micro- and nanofabrication allowing precision shaping at nanoscale.

    “This progress has been enabled by the advances in chemical vapour deposition (CVD) growth of single crystal diamond with the level of purity and low defect density required for quantum photonics, and by advances in micro-and nanofabrication, allowing for precision shaping of diamond at the nanoscale [61].”

    From 2022 Roadmap on integrated quantum photonics (2022) · cites this paper as [61]

    Section 5.1 says high-purity single-crystal diamond yields the best NV-center properties and that lithography and etching can pattern diamond surfaces. Section 5.2 uses a low-nitrogen CVD crystal, but the paper does not establish that advances in CVD growth and low defect density enabled the cited progress. The Introduction and section 5.1 instead emphasize continuing difficulties in fabricating diamond waveguides and cavities, particularly controlling their vertical structure. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
