Free-standing silicon nitride nanobeams with efficient fiber-chip interface for cavity QED
Abdulrahman Alajlan, Mohit Khurana, Xiaohan Liu +2
We present the design, fabrication and characterization of high quality factor silicon nitride nanobeam PhC cavities at visible wavelengths for coupling to diamond color centers in…
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…
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…
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…
All-angle zero reflection at metamaterial surfaces
Xin Li, Zixian Liang, Xiaohan Liu +2
The authors study theoretically reflection on the surface of a metamaterial with a hyperbolic dispersion. It is found that reflection is strongly dependent on how the surface is te…
Enhanced transmission of optically thick metallic films at infrared wavelengths
Dezhuan Han, Xin Li, Fengqin Wu +1
For an optically thick metallic film, the transmission for both s- and p-polarized waves is extremely low. If the metallic film is coated on both sides with a finite dielectric lay…
