Finite size mediated radiative coupling of lasing plasmonic bound state in continuum

Benjamin O. Asamoah, Marek Nečada, Wenzhe Liu +12

Radiative properties of lasing plasmonic bound state in continuum are analyzed. The topological charge of the lasing signal is analyzed in the far field as well as in the source pl…

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…

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…

Observation of optical states below light cone with compound lattices

Jiajun Wang, Ang Chen, Maoxiong Zhao +5

For optical systems, states inside the light cone could be detected by far-field measurement, while those below the light cone are not detectable by far-field measurement. A new me…

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…
