Zusammenfassung

Nitrogen vacancy centers in diamond hold great potential for quantum sensing applications. The challenge of integration can be addressed by using integrated photonics based on modern nanofabrication techniques. Here, we present optically detected magnetic resonance measurements from deterministically embedded microdiamonds with NV centers in polymer waveguides on silicon substrates. In combination with electrically conductive microstructures for microwave supply, this method of optical access provides the basis for scaling up to highly integrated on-chip sensors with excellent spatial magnetic resolution and sensitivity.
