The discovery of photonic topological insulators (PTIs) has opened the door to fundamentally new topological states of light.Current time-reversal-invariant PTIs emulate either the quantum spin Hall (QSH) effect or the quantum valley Hall (QVH) effect in condensed-matter systems, in order to achieve topological transport of photons whose propagation is predetermined by either 'photonic pseudospin' (abbreviated as 'spin') or valley. Here we demonstrate a new class of PTIs, whose topological…

Spin- and valley-polarized one-way Klein tunneling in photonic topological insulators

A new class of photonic systems, described by effective Hamiltonians in which competing synthetic gauge fields, engineered in pseudospin, chirality/sublattice, and valley subspaces, result in bandgap opening at one of the valleys, whereas the other valley exhibits Dirac-like conical dispersion.

Valley photonic crystals for control of spin and topology.

This work proposes a concept of valley photonic crystals with electromagnetic duality symmetry but broken inversion symmetry, and shows the independent control of valley and topology in a single system that has been long pursued in electronic systems, resulting in topologically-protected flat edge states.
