Investigation of Tunable Structured Light Using Bilayer Parity-Time Symmetry Dammann Grating Metasurfaces
Xiang Cai, Zhiwei Shi, Wei Liu +3
In the current technological landscape, structured light technology holds a critically important position. However, traditional structured light optical components often require co…
Airy-soliton interactions in self-defocusing media with PT potentials
Zhiwei Shi, Huagang Li, Xing Zhu +1
We investigate Airy-soliton interactions in self-defocusing media with PT potentials in one transverse dimension. We discuss different potentials in which the interacting beams wit…
Surface solitons in PT symmetric potentials
Huagang Li, Zhiwei Shi, Xiujuan jiang +2
We investigate light beam propagation along the interface between linear and nonlinear media with parity-time PT symmetry, and derive an equation governing the beam propagation. A…
Nonparaxial spatial optical solitons with nonlocality nonlinearity
Jilong Chen, Zhiwei Shi, Huagang Li
We investigate one-dimensional Helmholtz solitons with nonlocal nonlinearity. We show an exact analytical solution to the nonlocal nonlinear nonparaxial propagation equation in the…
