Perturbative analysis of generally nonlocal spatial optical solitons
Shigen Ouyang, Qi Guo, Wei Hu
In analogy to a perturbed harmonic oscillator, we calculate the fundamental and some other higher order soliton solutions of the nonlocal nonlinear Schroedinger equation (NNLSE) in…
Amphoteric refraction at the interface between isotropic and anisotropic media
Hailu Luo, Wei Hu, Xunong Yi +2
It is found that the amphoteric refraction, i.e. the refraction can be either positive or negative depending on the incident angles, could occur at a planar interface associated wi…
Focusing and phase compensation of paraxial beams by a left-handed material slab
Hailu Luo, Wei Hu, Zhongzhou Ren +2
On the basis of angular spectrum representation, a formalism describing paraxial beams propagating through an isotropic left-handed material (LHM) slab is presented. The treatment…
Nonlocality-controlled interaction of spatial solitons in nematic liquid crystals
Wei Hu, Tao Zhang, Qi Guo +2
We demonstrate experimentally that the interactions between a pair of nonlocal spatial optical solitons in a nematic liquid crystal (NLC) can be controlled by the degree of nonloca…
Superluminal group velocity in an anisotropic metamaterial
Hailu Luo, Wei Hu, Weixing Shu +2
Based on boundary condition and dispersion relation, the superluminal group velocity in an anisotropic metamaterial (AMM) is investigated. The superluminal propagation is induced b…
