Among all the platforms studied for integrating emitters in photonic devices, 2D materials are one of the most promising for on-demand single-photon sources (SPSs) because of their exceptional flexibility and unique optical response which has opened the way to employ mechanical deformation for engineering their physical properties. It has been theoretically proven that excitons can also be trapped by defect potentials as single-photon emitters in TMDCs monolayer, making defect engineering a promising approach to realize on-demand SPSs. Our findings reveal artificially engineering planar materials (metasurfaces) as the optimal electromagnetic environment to generate, control and manipulate SPSs from atomically thin layers.
Over the last two decades, the ability to achieve well-defined size, geometry, and distribution of plasmonic structures has extensively been studied. Here, we introduce a unique strained induced self-rolling fabrication technique suitable to fabricate three-dimensional multilayer thin film-based plasmonic devices. The photoresist-based technique enables the fabrication of nanohole arrays on SiO2/Au-based rolled-up tubes (RUTs). The curved nature of the tube allows the fabrication of an out-of-plane metasurface that can effectively control the light compared to the common planar counterparts.
Planar nanostructures, both dielectric and plasmonic, provide exceptional light manipulation at the subwavelength scale. Here, we introduce an out-of-plane nanohole-based nanostructure design with the implementation of a unique self-rolling technique.
