Exciting Reflectionless Unidirectional Edge Modes in a Reciprocal Photonic Topological Insulator Medium
Bo Xiao, Kueifu Lai, Yang Yu +3
Photonic topological insulators are an interesting class of materials whose photonic band structure can have a bandgap in the bulk while supporting topologically protected unidirec…

All-Si Valley-Hall Photonic Topological Insulator
Tzuhsuan Ma, Gennady Shvets
An all-Si photonic structure emulating the quantum-valley-Hall effect is proposed. We show that it acts as a photonic topological insulator (PTI), and that an interface between two…

Scattering-Free Optical Edge States between Heterogeneous Photonic Topological Insulators
Tzuhsuan Ma, Gennady Shvets
We propose a set of three simple photonic platforms capable of emulating quantum topologically insulating phases corresponding to Hall, spin-Hall, and valley-Hall effects. It is sh…
