[期刊论文] 作者:ShiqiangXia,DaohongSong,LiqinTang,CiboLou,YigangLi, 来源:ChineseOpticsLetters 年份:2013
Higher-band self-trapping and oscillation (rotation) of nonlinear quadruple beams in two-dimensional (2D) square photonic lattices are numerically demonstrated. Under appropriate conditions of nonlinearity, a quadruple-like beam can self-tr......

A Dirac point is a linear band crossing point originally used to describe unusual transport properties of materials like graphene. In recent years, there has been a surge of exploration of type-II Dirac/Weyl points using various engineered ......

We theoretically and experimentally study self-accelerating and self-breathing Bessel-like beams that follow arbitrary trajectories, including hyperbolic, hyperbolic secant, and three-dimensional (3D) spiraling trajectories. The beams have ......
