Expérimental et théorique Description
The aim of this project is to study the physics of “synthetic photonic materials”, which consist of synthetic platforms designed in the lab in order to make photons behave like matter particles. In our lab, we use photons trapped in micron-size semiconductor cavity as a building block to realize such materials. For example, by arranging an ensemble of microcavities in the form of a honeycomb lattice, it is possible to create “photonic graphene” structures, which are similar in every respect to the electronic band structure of real graphene.
In this project, we will build upon recent developments in the field of multilayer graphene, to investigate how these concepts transfer to photonic graphene. In particular, how is the band structure of photonic graphene modified when several vertically coupled cavities are stacked? In the presence of a torsion angle between the two layers, what is the impact of the Moiré effect caused by this superposition? Finally, what advantages can be derived from the additional degrees of freedom offered by the photonic platform, for example when the degeneracy between the different polarization states of light is lifted (effective spin-orbit coupling) or when light is coupled to electronic excitations of the semiconductor material?
