New Scanning nearfield Microscopy method bAsed on Radio-frequency Trap and LANthanide nanoprobe for LIGHT matter interaction.
Probing optical near field interactions provides valuable information on the surface and topology of nanoobjects and it is very important for characterizing and developing the future optical systems. However measuring these interactions is realized with the use of an extremely sharp tip. These tips are then approached very close to the nanometer scale object of interest or a surface and the changes of the scattered light are registered in function of the tip position. This technique works well and allows to measure very precise interaction of light matter at the nanoscale, however it is very difficult to work with a tip and the presence of the whole body of the tip in the measurement remains a fundamental problem. The SmartLanlight project aims at removing and replacing the tip by a nanometer scale object in levitation. To reach that goal we use electrical fields in order to manipulate and levitate the nanoparticle. Manipulation of nanoparticles with electric fields is only emerging in nanosciences. Two main objectives were identified in this project. The first was to master this levitation and manipulation technique with nanometric objects. The second was to manipulate the particle in levitation and to probe its optical properties when scanning a photonic structure. Besides these two objectives, we also worked on the printing of nanoparticles in levitation in air on a receiver substrate. This is actually important for the development of future all optical systems and quantum nanotechnologies.

Project objective
Measuring and controlling light-matter interactions at the nanoscale is critical for many applications affecting both scienceand society, ranging from disease detection and treatment to quantum-based information science. Performing studies ofthese interactions requires a nano source of light, high resolution detection and accurate three dimensional manipulation.However, most of the existing nano-optical techniques offer a subset, but not all, of these elements. We propose in this project to develop a system for measuring optical fields properties on nanostructures with nano-emitter levitating by a Paul also called radio-frequency trap. We will use -but not limited to- a lanthanide doped particle as the nano-emitter. Specifically, lanthanides are sensitive to both optical electric and magnetic field so that full understanding of the optical near-field properties is achievable, in an unprecedented way. We then plan to employ this new technique for investigating nanolight-matter interactions on technologically-important nanostructures such as optical antennas, nanophotonic circuits, metamaterials etc... This new and original probing technique will open the ways to a large variety of applications such as high resolution imaging of nanophotonics components (nano-optical circuiterie, spin domain, ...) or biological samples but also e.g cancer diagnostic and therapy since lanthanide can be used for tumor cell detection and photodynamic therapy.
