Scientists at RMIT University and the University of Adelaide have developed a diamond sensor using conventional fibers. They embedded μm-scale diamond particles within the cross-section of a silicate glass fiber. The diamond-doped optical fibers drive the fiber optic magnetometry with ensemble nitrogen-vacancy (NV) centers in diamond. The sensor can be used in the field.
Diamond containing an NV center is an important platform for quantum sensors, but most NV sensors require microscopes to collect the fluorescence signals. This limits their use to laboratory settings.
Heike Ebendorff-Heidepriem at the University of Adelaide said the research team worked to find a way around this issue for a decade. “Because diamond…READ MORE
