Nitrogen-vacancy (NV) centers in diamond have advanced to a highly promising nano-scale probe. A prominent feature of the NV center is optical initialization and readout of its spin degree of freedom, which can also be controlled via microwave fields. Due to low cytotoxicity, relatively long coherence times at room temperature, and its high sensitivity to external fields, it is widely used to detect DC and AC magnetic fields and to sense temperature distributions in biological samples.
We present the incorporation of nanodiamonds containing NV centers into direct-laser-written (DLW) three-dimensional polymer photonic structures on a fiber tip. In addition, we show our approach to integrate a microwave antenna for NV spin control manufactured with metal DLW to the same fiber tip and complement our studies with simulations performed in COMSOL. This paves the way to a fully integrated "Lab-on-Tip" for biological applications.
