Enhanced Single NV Arrays
Pillar Arrays
Single NV arrays with enhanced optical outcoupling
Make your single NV experiments easy and fast with our NV arrays. These consist of a diamond membrane with arrays of outcoupling structures mounted on a sapphire chip for easy handling. These structures are shaped to enhance the collection efficiency by more than 10x compared to bulk diamond, significantly increasing the signal-to-noise.
Enhanced emission
We significantly enhance the brightness of the single NVs by placing them in an approximately parabolic shape structure. Not only does this increase the saturation count rate into the MCts/s range, it also makes it easy to localize and adress the NVs. Whether for sensing, as a single photon source, or for quantum computing experiments, a more than 10x increase in brightness will significantly improve your experiment.
Product description
Our NV array chips consist of a diamond membrane with 36 arrays of 200 by 200 NV sites, mounted on a saphirre chip for easy handling. You can expect about 30% of sites to have a single NV and about 5% to have a high perfoming one. To help you get started, we precharacterize NV arrays and provide you with a map of NV sites and their performance.
Coherence times significantly depend on the NV depth, where deeper is better. We offer two different depths:
- Shallow: target depth is 8 nm, for surface sensing applications, such as NMR.
- Medium: target depth is 50(100) nm for applications such as single photon sources, magnetic field sensing and quantum computing.
Get in touch with us for specific request, such as surface annealing, additional characterization, isotopically pure material or higher C13 content.

How to order
1. Choose a depth: shallow for surface sensing, or deep if you plan NV experiments that profit from longer coherence.
2. Get in touch with us for different NV orientations (in-plane/out-of-plane) or isotopically pure C12 arrays.
