Discrete wavelet structure and discrete energy of a classical plane light wave
Xingchu Zhang, Weilong She
In this letter, the wavelet transform is used to decompose the classical linearly polarized plane light wave into a series of discrete Morlet wavelets. It is found that the energy…
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…
Interaction of Airy-Gaussian beams in defected photonic lattices
Zhiwei Shi, Jing Xue, Xing Zhu +2
We investigate interactions by means of direct numerical simulations between two finite Airy-Gaussian (AiG) beams in different media with the defected photonic lattices in one tran…
Propagation of an Airy-Gaussian beam in defected photonic lattices
Zhiwei Shi, Jing Xue, Xing Zhu +2
We investigate numerically that a finite Airy-Gaussian (AiG) beam varies its trajectory and shape in the defected photonic lattices. The propagation properties and beam self-bendin…
Bulk vortices and half-vortex surface modes in parity-time-symmetric media
Huagang Li, Xing Zhu, Zhiwei Shi +3
We demonstrate that in-bulk vortex localized modes, and their surface half-vortex ("horseshoe") counterparts self-trap in two-dimensional (2D) nonlinear optical systems with $\math…
Nonlocal bright spatial solitons in defocusing Kerr media supported by PT symmetric potentials
Zhiwei Shi, Huagang Li, Xing Zhu +1
It is studied the bright spatial solitons in nonlocal defocusing Kerr media with parity-time (PT) symmetric potentials. We find that these solitons can exist and be stable over a d…
