Exciting News from the Mikkelsen Lab!
Our latest work has been selected for the cover of ACS Nano! We're thrilled to have this research featured in the May 2025 issue. 🙌
In this study, we demonstrate ultrafast single-photon emission from silicon vacancy centers in a diamond membrane—achieving picosecond lifetimes at room temperature using plasmonic nanogap cavities.
Highlights include:
• 5.5 ps ultrafast lifetime
• Purcell enhancement >700×
• 361 Mcps single-photon generation rate
• 4800× brightness increase
This breakthrough in nanocavity engineering could accelerate the development of scalable quantum photonic technologies such as quantum communication, quantum key distribution, and all-photonic computing.
Many thanks to our amazing team:
