A Group-Theoretical Framework for Local k-Space Topology and Berry Phase in 2D Photonic Systems
Xinyi Yuan, Grazia Salerno
Two-dimensional photonic crystals (2D PhCs) enable fine-grained control over a broad set of Bloch modes without the constraints of band occupancy and natural crystal structures, an…
Topological photonics in nanoscaled systems with far field radiation and polarization singularities
Grazia Salerno
Topology is a powerful framework for controlling and manipulating light, minimizing detrimental perturbations on the photonic properties. Combining nanophotonics with topological c…
Topological invariants and topological charges in photonic systems
Kristian Arjas, Grazia Salerno, Päivi Törmä
Topology in photonics comes in two distinct flavors: global and local. Global topology considers invariants that are obtained by integrating over the energy band, whereas local top…
Breakdown of Bulk-Radiation Correspondence in Radiative Photonic Lattices
Xinyi Yuan, Loïc Malgrey, Helgi Sigurðsson +2
The topological characteristics of energy bands in crystalline systems are encapsulated in the Berry curvature of the bulk Bloch states. In photonic crystal slabs, far-field emissi…
Condensation dynamics in a two-dimensional photonic crystal waveguide
Maria Efthymiou-Tsironi, Antonio Gianfrate, Dimitrios Trypogeorgos +6
Exciton-polariton condensation occurs at the extrema of the underlying dispersion where the density of states diverges and carriers can naturally accumulate. The existence of multi…
