The reversibility of the Goos-Hänchen shift near the band-crossing structure of one-dimemsional photonic crystals containing left-handed metamaterials
Li-Gang Wang, Shi-Yao Zhu
We perform a theoretical investigation on the Goos-Hächen (GH) shift in one-dimensional photonic crystals (1DPCs) containing left-handed metamaterials (LHMs). We find an unusal eff…
Hanbury Brown-Twiss effect and thermal light ghost imaging
Li-Gang Wang, Sajid Qamar, Shi-Yao Zhu +1
We show that the essential physics of the Hanbury Brown-Twiss (HBT) and the thermal light ghost imaging experiments is the same, i.e., due to the intensity fluctuations of the ther…
Fidelity, purity and entanglement of two-mode spatially Gaussian-entangled light fields in Turbulence Atmosphere
Li-Gang Wang, Shi-Yao Zhu
In this paper, we investigate the propagation of two-mode spatially Gaussian-entangled quantum light fields passing through the turbulence atmosphere. From the propagation formula…
Formation of optical vortices using coherent laser beam arrays
Li-Gang Wang, Li-Qin Wang, Shi-Yao Zhu
We present a novel proposal to generate an optical vortex beam by using the coherent-superposition of multi-beams in a radial symmetrical configuration. In terms of the generalized…
Effect of Coherence on Radiation Forces acting on a Rayleigh Dielectric Sphere
Li-Gang Wang, Cheng-Liang Zhao, Li-Qin Wang +2
The radiation forces on a Rayleigh dielectric sphere induced by a partially coherent light beam are greatly affected by the coherence of the light beam. The magnitude of the radiat…
Superluminal pulse reflection from a weakly absorbing dielectric slab
Li-Gang Wang, Shi-Yao Zhu
Group delay for a reflected light pulse from a weakly absorbing dielectric slab is theoretically investigated, and large negative group delay is found for weak absorption near a re…
