Photonic Jets and Single‐Photon Emitters

Photonic jets (PJs) obtained by illuminating a dielectric microsphere have recently shown to provide an efficient and cost‐effective means of laser‐writing localizing single‐photon emitters with sub‐diffraction precision. The fabrication technique relies on the photoinduced formation GaAsN quantum dots (QDs) that are self‐aligned microsphere, which in turn enhances collection efficiency their emission. Similarly, angular magnification introduced placed top two close allows detect resolve separation below diffraction limit analyzing emission pattern momentum space. Along brief review methods, systematic numerical study properties PJs streamline optimization process is presented.
