    An efficient way of realising a large number of telecom single-photon emitters for quantum communication is still missing. Here, the authors use a wide-field imaging technique for fast localization of single InAs/InP quantum dots, which are then integrated into circular Bragg grating cavities featuring high single-photon purity and indistinguishability.

    Fano resonant optical coatings (FROCs) present an ideal platform for structural coloring from thin-film metamaterials. This platform provides full-color gamut coverage at greater than 61% of the CIE gamut, with exceptionally high purity (up to 99%) and high brightness. FROCs exhibit tunable iridescence, cost-effective and scalable manufacturing, and significant advantages over existing structural coloring schemes.
