“…By combining a diamond microcrystal coupled to a 200 μm core diameter optical fibre. Fedotov et al recently built a compact magnetometer based on a similar structure. To improve the sensitivity of this kind of device, high quality bulk diamond crystals synthesised by means of chemical vapour deposition (CVD) process could be used instead of diamond microcrystals since their synthesis is now well mastered but also because intrinsic NV centres exhibit generally far better spin coherence properties.…”

Nitrogen-vacancy (NV) colour centre in diamond is a very promising tool for sensing applications from magnetometry to thermometry. In this paper, we demonstrate a compact and convenient device for magnetic-field sensing where a commercial single-mode photonic crystal fibre is directly coupled to a commercial high quality diamond sample synthesised by means of chemical vapour deposition process and containing a residual nitrogen impurity rate smaller than 1 part per million. We managed to excite and detect efficiently the photoluminescence from an ensemble of NV centres and to perform electron spin resonance experiments where the NV hyperfine structure is perfectly resolved under continuous measurement.

The flat endface of an optical fiber tip is an emerging light-coupled microscopic platform that combines fiber optics with planar micro-and nanotechnologies. Since different materials and structures are integrated onto the endfaces, optical fiber tip devices have miniature sizes, diverse integrated functions, and low insertion losses, making them suitable for all-optical networks. In recent decades, the increasing demand for multifunctional optical fibers has created opportunities to develop various structures on fiber tips. Meanwhile, the unconventional shape of optical fibers presents challenges involving the adaptation of standard planar micro-and nanostructure preparation strategies for fiber tips. In this context, researchers are committed to exploring and optimizing fiber tip manufacturing techniques, thereby paving the way for future integrated all-fiber devices with multifunctional applications. First, we present a broad overview of current fabrication technologies, classified as "top-down," "bottom-up," and "material transfer" methods, for patterning optical fiber tips. Next, we review typical structures integrated on fiber tips and their known and potential applications, categorized with respect to functional structure configurations, including "optical functionalization" and "electrical integration." Finally, we discuss the prospects for future opportunities involving multifunctional integrated fiber tips.

“…Nevertheless, the sophistication and lack of portability of such high-end microscopes has led to interest in integrating diamond NV centers with glass optical fibers. To date, the most commonly used approach to realize such a hybrid device relies on growing or placing diamond materials external to the fiber, [11][12][13][14] which enables NV emitters to locate either on the endface of the fiber [15][16][17] or tapered fiber regions. [18][19][20] Diamond nanoparticles have been combined with tellurite (Te) glass to create hybrid diamond-glass fibers, [21] and Mayani et al demonstrated distributed diamond-fiber magnetometry by periodically spacing photodiode chips along a polycarbonate cladding to detect the diamond-microfluidic systems configurated in a hollow-core silica fiber.…”

Fluorescent diamond microparticle doped glass fiber for magnetic field sensing

et al. 2020

View full text Add to dashboard Cite

Diamond containing the negatively charged nitrogen-vacancy (NV) center is emerging as a significant new system for magnetometry. However, most NV sensors require microscopes to collect the fluorescence signals and are therefore limited to laboratory settings. By incorporating micron-scale diamond particles at an annular interface within the cross section of a silicate glass fiber, a high-sensitivity and robust fiber platform for magnetic field sensing is demonstrated here. The fluorescence and spin properties of NV centers embedded in the diamond crystals are well preserved during the fiber drawing process, leading to enhanced continuous-wave diamond-magnetometry in fiber-transmitted sensing configurations. The interface doping of diamond particles also leads to reduced fiber propagation loss and benefits the guidance of NV-fluorescence in the hybrid fiber. Using the diamond-fiber system, magnetic field readout through 50 cm of fiber is achieved. This study paves the way for novel fiber-based diamond sensors for field-deployable quantum metrology applications.
