A monolithic immersion metalens for imaging solid-state quantum emitters.... Quantum emitters such as the diamond nitrogen-vacancy (NV) center are the basis for a wide range of quantum technologies.However, refraction and reflections at material interfaces impede photon collection, and the emitters’ atomic scale necessitates the use of free space optical measurement setups that prevent packaging of quantum devices. To overcome these limitations, we design and fabricate a metasurface composed of nanoscale diamond pillars that acts as an immersion lens to collect and collimate the emission of an individual NV center. #monolithic #immersion #metalens #imaging #solid-state #quantum #emitters #photonic #optic #physics #chemistry #diamond #nitrogen-vacancy #NV #light #technology #hardware (...)
