Abstract
The efficient interaction of light with quantum emitters is crucial to most applications in nano and quantum technologies. Effective excitation and collection are key ingredients for the use and manipulation of the generated single photons. We have recently demonstrated how single molecules as quantum emitters can be deposited in a planar optical antenna, resulting in a narrow radiation pattern and increased collection efficiency [1]. On-chip integration and miniaturization allows for minimized losses and tailored interaction. In the present contribution we demonstrate the deterministic integration in 3-dimensional polymeric structures of single quantum emitters close to the lifetime limit. This is achieved by 3D Laser Writing (3DLW) of commercial photoresists around self-assembled organic nanocrystals containing fluorescent molecules. Thanks also to the high 3D resolution of the two-photon absorption process, this solution offers a big advantage in terms of coupling efficiency of the emitted fluorescence to the photonic structure.
