Experimental Physics V

Nano-Optics and Biophotonics


Our mission is to obtain fundamental control over light-matter interaction by controlling the flow of photons at the nanometer scale down to the size of single atoms, molecules, and quantum dots. We use optical nanoantennas and related plasmonic nanostructures as enabling devices.

We rely on our ability to fabricate high-end single-crystalline gold nanostructures based on large, but very thin chemically grown single-crystal gold flakes. Using top-down nanostructuring methods, such as focused ion-beam milling, we strive to obtain highest quality gold nanostructures with close to atomic precision.
