Topological moiré polaritons
I. Septembre, C. Leblanc, D. D. Solnyshkov +1
The combination of an in-plane honeycomb potential and of a photonic spin-orbit coupling (SOC) emulates a photonic/polaritonic analog of bilayer graphene. We show that modulating t…

Soliton formation in an exciton-polariton condensate at a bound state in the continuum
I. Septembre, I. Foudjo, V. Develay +5
Bound states in the continuum (BIC) are of special interest in photonics due to their theoretically infinite radiative lifetime. Here, we design a structure composed of a GaN layer…

Towards analogue black hole merger
Dmitry Solnyshkov, Ismaël Septembre, Guillaume Malpuech
We study the effects of the wavevector-dependent losses on polariton condensates. We demonstrate that because of these losses, a single vortex becomes a center of a convergent flow…
