Quantum nanophotonics

Scientific activity

The work of the Quantum Nanophotonics (QNP) division focuses primarily on the study of nanosources of light:

• Colored centers in large-gap semiconductor nanostructures (ZnO, hBN);
• CdSe-based colloidal semiconductor nanocrystals, at the scale of individual objects or self-assembled into aggregates;
• Low-dimensional hybrid perovskites.

We are also examining their coupling to photonic structures, in particular plasmonic structures whose resonance modes are confined to distances of a few nanometers.

In the context of integrated quantum photonics, the aim is to realize single-photon sources with excellent properties in terms of brightness and indiscernibility, in a fully controlled fabrication process.
