NV-centers as single-photon emitters integrated into three-dimensional laser-written micro-structures — •Andreas W.

Future quantum-optical experiments and applications will likely require on-chip integration of micro-optical structures and single-photon emitters. Here, we show the direct integration of nitrogen-vacancy centers (NV centers) in nanodiamonds into various three-dimensional photonic structures by means of two-photon direct laser writing [1]. This technique enables manufacturing micro-optical structures of nearly arbitrary shape. The nanodiamonds are integrated by mixing them into the photoresist prior to its exposure. To exemplify the strength of this approach, we demonstrate efficient coupling of NV centers serving as single-photon sources to waveguides and whispering-gallery-mode optical micro-resonators.
