Routing of valley photons in a WS2 monolayer via delocalized Bloch modes of in-plane inversion-symmetry broken photonic crystal slabs
Jiajun Wang, Han Li, Yating Ma +8
The valleys of two-dimensional transition metal dichalcogenides (TMDCs) offer a new degree of freedom for information processing. To take advantage of this valley degree of freedom…
Vector exceptional points with strong superchiral fields
Tong Wu, Weixuan Zhang, Huizhen Zhang +12
Exceptional points(EPs), branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce, are ubiquitous in non-Hermitian systems. Many novel properties and…
Generating optical vortex beams by momentum-space polarization vortices centered at bound states in the continuum
Bo Wang, Wenzhe Liu, Maoxiong Zhao +7
An optical vortex (OV) is a beam with spiral wave front and screw phase dislocation. This kind of beams is attracting rising interest in various fields. Here we theoretically propo…
Circularly polarized states spawning from bound states in the continuum
Wenzhe Liu, Bo Wang, Yiwen Zhang +6
Bound states in the continuum in periodic photonic systems like photonic crystal slabs are proved to be accompanied by vortex polarization singularities on the photonic bands in th…
Observing half and integer polarization vortices at band degeneracies
Ang Chen, Wenzhe Liu, Yiwen Zhang +6
Far-field polarization vortices were recently found on singlet bands in the momentum-space of two-dimensional photonic lattices, also known as the dark states and bound states in c…
Observation of optical vortices in momentum space
Yiwen Zhang, Ang Chen, Wenzhe Liu +6
Vortex, the winding of a vector field in two dimensions, has its core the field singularity and its topological charge defined by the quantized winding angle of the vector field. V…
