Spectral edge-to-edge topological state transfer in diamond photonic lattices
Gabriel Cáceres-Aravena, Bastián Real, Diego Guzmán-Silva +5
Transfer of information between topological edge states is a robust way of spatially manipulating quantum states while preserving their coherence in lattice environments. This meth…

Scattering-matrix approach for a quantitative evaluation of the topological protection in valley photonic crystals
Gaëtan Lévêque, Yan Pennec, Pascal Szriftgiser +2
In this work, we use valley-topological triangular resonators coupled to an input waveguide to evaluate the quality of the topological protection. To that purpose, we first analyze…
