Dynamically reconfigurable topological routing in nonlinear photonic systems
Stephan Wong, Simon Betzold, Sven Hofling +1
The propagation path of topologically protected states is bound to the interface between regions with different topology, and as such, the functionality of linear photonic devices…
Topological photonic crystal fibre
Bofeng Zhu, Kevin Hean, Stephan Wong +8
Photonic crystal fibres (PCFs) are optical fibres that guide light using a modulated dielectric medium. They provide an exceptionally versatile platform for various applications, t…
Quantitative measure of topological protection in Floquet systems through the spectral localizer
Stephan Wong, Alexander Cerjan, Justin T. Cole
The standard understanding of topological protection from band theory is that a system's topology cannot change without first closing the bulk band gap. However, in Floquet systems…
Classifying topology in photonic crystal slabs with radiative environments
Stephan Wong, Terry A. Loring, Alexander Cerjan
In the recent years, photonic Chern materials have attracted substantial interest as they feature topological edge states that are robust against disorder, promising to realize def…
