On-demand longitudinal transformations of light beams via an amplitude-phase-decoupled Pancharatnam-Berry phase element
Yu Zou, Yanke Li, Jialong Yan +7
Overcoming the inherent phase-only modulation limitation of conventional Pancharatnam-Berry (PB) elements, we propose a checkerboard-encoded PB element that enables simultaneous am…
Hybrid vector beams with non-uniform orbital angular momentum density induced by designed azimuthal polarization gradient
Lei Han, Shuxia Qi, Sheng Liu +3
Based on angular amplitude modulation of orthogonal base vectors in common-path interference method, we propose an interesting type of hybrid vector beams with unprecedented azimut…
Optically active beams: non-reciprocal optical activity in free space induced by spin-orbital interaction of light
Sheng Liu, Shuxia Qi, Peng Li +9
Optical activity, the power of a medium to rotate the polarization of a light beam, has contributed significantly to molecular structure assessments in stereochemistry, biomolecula…
Valley vortex states and degeneracy lifting via photonic higher-band excitation
Daohong Song, Daniel Leykam, Jing Su +7
We demonstrate valley-dependent vortex generation in a photonic graphene. Without breaking the inversion symmetry, excitation of two equivalent valleys leads to formation of an opt…
Unveiling pseudospin and angular momentum in photonic graphene
Daohong Song, Vassilis Paltoglou, Sheng Liu +7
Pseudospin, an additional degree of freedom inherent in graphene, plays a key role in understanding many fundamental phenomena such as the anomalous quantum Hall effect, electron c…
Generation of vector beams in planar photonic crystal cavities with multiple missing-hole defects
Chenyang Zhao, Xuetao Gan, Sheng Liu +2
We propose a novel method to generate vector beams in planar photonic crystal cavities with multiple missing-hole defects. Simulating the resonant modes in the cavities, we observe…
Beam steering and topological transformations driven by interactions between discrete vortex and fundamental solitons
Xuetao Gan, Peng Zhang, Sheng Liu +2
We study coherent and incoherent interactions between discrete vortex and fundamental solitons in two-dimensional photonic lattices, presenting a new scheme for all-optical routing…
Mesons and Nucleons in Soft-Wall AdS/QCD with Constrained Infrared Background
Sheng Liu, Peng Zhang
The purpose of this paper is to further study the soft-wall AdS/QCD model with constrained IR background. By including a quartic bulk scalar potential we study various meson and nu…
