Open AccessAntichiral surface states in time-reversal-invariant photonic semimetals
Besides chiral edge states, the hallmark of quantum Hall insulators, antichiral edge states can exhibit unidirectional transport behavior but in topological semimetals. Although such edge states provide more f...

Open AccessA silicon-on-insulator slab for topological valley transport
Backscattering suppression in silicon-on-insulator (SOI) is one of the central issues to reduce energy loss and signal distortion, enabling for capability improvement of modern information processing systems. ...

Open AccessFull Polarization Conical Dispersion and Zero-Refractive-Index in Two-Dimensional Photonic Hypercrystals
Photonic conical dispersion has been found in either transverse magnetic or transverse electric polarization and the predominant zero-refractive-index behavior in a two-dimensional photonic crystal is polariza...

Open AccessFull controlling of Fano resonances in metal-slit superlattice
Controlling of the lineshape of Fano resonance attracts much attention recently due to its wide capabilities for lasing, biosensing, slow-light applications and so on. However, the controllable Fano resonance ...

Open AccessSymmetry-protected transport in a pseudospin-polarized waveguide
If a system possesses a spin or pseudospin, which is locked to the linear momentum, spin-polarized states can exhibit backscattering-immune transport if the scatterer does not flip the spin. Good examples of s...

Open AccessDirac directional emission in anisotropic zero refractive index photonic crystals
A certain class of photonic crystals with conical dispersion is known to behave as isotropic zero-refractive-index medium. However, the discrete building blocks in such photonic crystals are limited to constru...
