Localized Photon Lasing in a Polaritonic Lattice Landscape

Daniel Oberli, Marcia Portella Oberli, Fauzia Jabeen, Morteza Navadeh Toupchi

Periodic photonic structures have attracted much interest due to their versatility for controlling light propagation. The dispersion of photon modes in photonic lattices exhibits an energy band structure analo-gous to the electronic one in crystals. An imp ...

Quantitative robustness analysis of topological edge modes in C6 and valley-Hall metamaterial waveguides

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev

Recent advances in designing time-reversal-invariant photonic topological insulators have been extended down to the deep subwavelength scale, by employing synthetic photonic matter made of dense periodic arrangements of subwavelength resonant scatterers. I ...

Uncoupled photonic band gaps

We theoretically investigated the symmetry properties of the modes in two-dimensional square lattice photonic crystals in order to study phenomena that would enable new frontiers in the applications of photonic crystals. Using group theory, symmetry analys ...

A novel formalism for the study of the electronic and optical properties of high symmetry heterostructures

Sascha Dalessi

The theories used up to now to model theoretically and numerically nanostructures, and more specifically semiconductor heterostructures, do not allow to include efficiently at the envelope function level, in a k · p approach, the effects imposed by a possi ...
