We introduce an alternative scheme for creating topological polaritons (topolaritons) by exploiting the presence of photonic Dirac cones in photonic crystals with triangular lattice symmetry. As recently proposed, topolariton states can emerge from a coupling between photons and excitons combined with a periodic exciton potential and a magnetic field to open up a topological gap. We show that in photonic crystals the opening of the gap can be substantially simplified close to photonic Dirac…

It is demonstrated that honeycomb arrays of microcavity pillars behave as an optical-frequency two-dimensional photonic topological insulator and the interplay between the photonic spin-orbit coupling natively present in this system leads to the opening of a nontrivial gap characterized by a C=±2 set of band Chern numbers.
Observation of unidirectional backscattering-immune topological electromagnetic states
It is demonstrated that, like their electronic counterparts, electromagnetic CESs can travel in only one direction and are very robust against scattering from disorder; it is found that even large metallic scatterers placed in the path of the propagating edge modes do not induce reflections.
