Topological charge engineering in lasing bound states in continuum
Sughra Mohamed, Jie Wang, Heikki Rekola +4
Recently, optical bound states in continuum in various passive photonic crystals have been identified and similar structures incorporated with optical gain have been reported to ex…
Topological Polarization Singularities in Metaphotonics
Wenzhe Liu, Wei Liu, Lei Shi +1
Polarization singularities of vectorial electromagnetic fields locate at the positions (such as points, lines, or surfaces) where properties of polarization ellipses are not define…
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…
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…
Electromagnetic Scattering Laws in Weyl Systems
Ming Zhou, Lei Ying, Ling Lu +3
Wavelength determines the length scale of the cross section when electromagnetic waves are scattered by an electrically small object. The cross section diverges for resonant scatte…
