By embedding micron-scale diamond particles at an annular interface within the cross section of a silicate glass fiber, researchers in Australia demonstrated a robust fiber material capable of sensing magnetic fields. NV centers in the diamond microcrystals are well preserved throughout the fiber drawing process. The hybrid fiber presents a low propagation loss of ∼4.0 dB/m in the NV emission spectral window, permitting remote monitoring of the optically detected magnetic resonance signals. They demonstrated NV-spin magnetic resonance readout through 50 cm of fiber. The study paves a way for the scalable fabrication of fiber-based diamond sensors for field-deployable quantum metrology applications…read more. Open Access TECHNICAL ARTICLE
