Two-dimensional lattices of coupled micropillars etched in a planar semiconductor microcavity offer a workbench to engineer the band structure of polaritons. We report experimental studies of honeycomb lattices where the polariton low-energy dispersion is analogous to that of electrons in graphene. Using energy-resolved photoluminescence, we directly observe Dirac cones, around which the dynamics of polaritons is described by the Dirac equation for massless particles. At higher energies, we… Expand

Coupled micropillars etched in semiconductor microcavities are an excellent platform to engineer the properties of exciton-polaritons. Thanks to the direct optical access characteristic ofExpand
Quantum confinement of exciton-polaritons in a structured (Al,Ga)As microcavity
The realization of quantum functionalities with polaritons in an all-semiconductor platform requires the control of the energy and spatial overlap of the wave functions of single polaritons trappedExpand
Nonlinear Polariton Fluids in a Flatband Reveal Discrete Gap Solitons.
TLDR
The experimental investigation of the nonlinear response of cavity polaritons in the gapped flatband of a one-dimensional Lieb lattice results in the formation of gap solitons with quantized size and abrupt edges, a signature of the frozen propagation of switching fronts. Expand
Edge states in polariton honeycomb lattices
The experimental study of edge states in atomically-thin layered materials remains a challenge due to the difficult control of the geometry of the sample terminations, the stability of dangling bondsExpand
Spin-Orbit Coupling for Photons and Polaritons in Microstructures
We use coupled micropillars etched out of a semiconductor microcavity to engineer a spin-orbit Hamiltonian for photons and polaritons in a microstructure. The coupling between the spin and orbitalExpand
Ultrafast exciton-polariton scattering towards the Dirac points.
TLDR
Nonlinear polariton-polariton scattering in a two-dimensional micropillar-based optical superlattice with hexagonal symmetry is studied to demonstrate that in such a design the time of polariton scattering towards the Dirac points can be drastically decreased. Expand
Kagome lattice from an exciton-polariton perspective
We study a system of microcavity pillars arranged into a kagome lattice. We show that polarization-dependent tunnel coupling of microcavity pillars leads to the emergence of the effective spin-orbitExpand
Type-III and Tilted Dirac Cones Emerging from Flat Bands in Photonic Orbital Graphene
The extraordinary electronic properties of Dirac materials, the two-dimensional partners of Weyl semimetals, arise from the linear crossings in their band structure. When the dispersion around theExpand
Observation of Dirac bands in artificial graphene in small-period nanopatterned GaAs quantum wells
TLDR
The realization of an AG that has a band structure with vanishing density of states consistent with the presence of MDFs is reported, enabled by a very small lattice constant of the nanofabricated AG patterns superimposed on a two-dimensional electron gas hosted by a high-quality GaAs quantum well.
