Broadband optical nonreciprocity via nonreciprocal band structure
Ning Hu, Zhi-Xiang Tang, Xun-Wei Xu
As a promising approach for optical nonreciprocity without magnetic materials, optomechanically induced nonreciprocity has great potential for all-optical controllable isolators an…
Zitterbewegung-like effect near the Dirac point in metamaterials and photonic crystals
Xiaohui Ling, Zhixiang Tang, Hailu Luo +4
We present a physical explanation of Zitterbewegung-like effect near the zero-refractive-index point in a metamaterial slab in this paper. Between the negative and positive refract…
Generation of optical beams with desirable orbital angular momenta by transformation media
Weixing Shu, Dongmo Song, Zhixiang Tang +5
We propose a scheme to controllably convert the wavefront of an arbitrary incident beam into a helical one by compact transformation slabs, thus enabling the output beam to carry d…
Three-dimensional Negative-Refractive-Index Metamaterials Based on All-Dielectric Coated Spheres
Na Fu, Weixing Shu, Hailu Luo +4
A type of 3-dimensional optical negative-refractive-index metamaterials composed of all dielectric nanospheres is proposed and demonstrated theoretically. The metamaterials are con…
Spin Hall effect of a light beam in left-handed materials
Hailu Luo, Shuangchun Wen, Weixing Shu +3
We establish a general propagation model to describe the spin Hall effect of light beam in left-handed materials (LHMs). A spin-dependent shift of the beam centroid perpendicular t…
Are photon momenta in left-handed materials reversed?
Hailu Luo, Shuangchun Wen, Weixing Shu +3
We develop a semiclassical theory to describe the photon momenta in left-handed materials (LHMs). A single two-level atom is introduced as an "explorer" to probe the momenta of pho…
