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…
Intense Dark Exciton Emission from Strongly Quantum Confined CsPbBr Nanocrystals
Daniel Rossi, Xiaohan Liu, Yangjin Lee +6
Dark ground state exciton in semiconductor nanocrystals has been a subject of much interest due to its long lifetime attractive for applications requiring long-lived electronic or…
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…
