Controllable nonlinear propagation of partially incoherent Airy beams
Kaijian Chen, Peiyu Zhang, Nana Liu +5
The self-accelerating beams such as the Airy beam show great potentials in many applications including optical manipulation, imaging and communication. However, their superior feat…
Photocurrent imaging of hybrid polaritons in graphene based heterostructures
Weiwei Luo, Jialin Qi, Linglong Zhang +8
Photocurrent is arising as a powerful tool for detecting in-plane collective excitations in hybrid polariton systems. In this paper, based on the intrinsic optoelectric response of…
Photonic realization of a generic type of graphene edge states exhibiting topological flat band
Shiqi Xia, Yongsheng Liang, Liqin Tang +3
Cutting a honeycomb lattice (HCL) can end up with three types of edges (zigzag, bearded and armchair), as is well known in the study of graphene edge states. Here we theoretically…
Mapping and manipulation of topological singularities: from photonic graphene to T-graphene
Sihong Lei, Shiqi Xia, Junqian Wang +6
Topological singularities (TSs) in momentum space give rise to intriguing fundamental phenomena as well as unusual material properties, attracting a great deal of interest in the p…
