Nanometric ultrabright light sources
Many quantum information protocols rely on photons manipulation. Besides, quantum technologies require device miniaturization. Therefore, it is crucial to develop light nanosources which can be included within a quantum circuit. The Nanostructures and Optics team has realized optical nanosources based on the coupling of a single nanoemitter to a plasmonic nanoantenna in order to optimize its emission.
Caption: Patch antenna with a single nanoemittor The single emitter is located inside a transparent material, between a gold thick layer and a patch, which transmits emitted light. In-situ optical lithography makes it possible to position exactly at the nanometric scale the emitter inside antenna, and to optimize its emission.
