In order for quantum communication to become realistic with an implementation at a large scale, it is absolutely critical to be able to miniaturize the elements that will be parts of the future networks. In optics, miniaturization of photonics devices, widely called nanophotonics, is a very active research topic.
During the last decade, multiple Nano-optics and nanophotonics devices that outperform their traditional counterparts (faster operations, lower energy consumption…) have been demonstrated.
The new challenging task that we are now facing is to couple different devices at a nanometric scale in order to surpass their individual properties. These hybrid systems will then allow us to observe new physics effects and to develop innovative devices.
In the NanoOptics Team, we investigate original approaches for coupling optical fibers or more generally waveguides to various solid-state quantum emitters (semiconductor nanocrystals, nanodiamonds…).
The NanoOptics Team works on 3 main project :
- Q-crystals : Quantum Optics with high-quality semiconductor nanocrystals
- COSINE : Nanophotonics structures with optical nanofibers
- Nano² : Quantum nano-emitters coupled to nanofibers
