Fleming pioneered microstructured polymer optical fibre and continues to work on specialty fibre fabrication: drawing exotic polymer, hybrid polymer-metal and poled-silicate structures that would be impossible in conventional silica, and using them to build metamaterials and biomedical photonic devices including fibre-based sensors and probes. The fabrication route — preform drawing — gives access to geometries and material combinations that lithography cannot reach. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — the relevance to a sensing postdoc is delivery and packaging: fibre-integrated probes are the standard way to get an NV or vapour-cell sensor into a biological or field environment while preserving its pT/sqrt(Hz) sensitivity.
