Topological photonics is an emerging field of research, which is inspired by the discovery of
topological insulators. The introduction of topology endows traditional photonic systems with …

The quantum spin Hall effect lays the foundation for the topologically protected manipulation
of waves, but is restricted to one-dimensional-lower boundaries of systems and hence limits …

Photonic crystals offer unprecedented opportunity for light manipulation and applications in
optical communication and sensing,,,. Exploration of topology in photonic crystals and …

The valley has been exploited as a binary degree of freedom to realize valley-selective Hall
transport and circular dichroism in two-dimensional layered materials, in which valley …

Topological photonic states, inspired by robust chiral edge states in topological insulators,
have recently been demonstrated in a few photonic systems, including an array of coupled …

Valley photonic crystals (VPhCs) are an attractive platform for the implementation of
topologically protected optical waveguides in photonic integrated circuits (PICs). The …

Weyl particles are elusive relativistic fermionic particles with vanishing mass. While not
having been found as an elementary particle, they are found to emerge in solid-state …

We experimentally demonstrate topological slow light waveguides in valley photonic crystals
(VPhCs). We employed a bearded interface formed between two topologically-distinct …

The discovery of topological insulators was rapidly followed by the advent of their photonic
analogues, motivated by the prospect of backscattering‐immune light propagation. So far …
