Quantum effect of one-dimensional photonic crystal
Xiang-Yao Wu, Ji Ma, Xiao-Jing Liu +5
In this paper, we have studied the quantum transmission characteristics of one-dimensional photonic crystal with and without defect layer by the quantum theory approach, and compar…
Ultra-compact and broadband tunable mid-infrared multimode interference splitter based on graphene plasmonic waveguide
Ruiqi Zheng, Dingshan Gao, Jianji Dong
We propose and design an ultra-compact and broadband tunable multimode interference (MMI) splitter in mid-infrared based on graphene plasmonic waveguides. The size of the device is…
Optical force on toroidal nanostructures: toroidal dipole versus renormalized electric dipole
Xu-Lin Zhang, S. B. Wang, Zhifang Lin +2
We study the optical forces acting on toroidal nanostructures. A great enhancement of optical force is unambiguously identified as originating from the toroidal dipole resonance ba…
Revival and splitting of a Gaussian beam in gradient index media
V. Arrizon, F. Soto-Eguibar, A. Zuñiga-Segundo +1
The short range revival of an arbitrary monochromatic optical field, which propagates in a quadratic GRIN rod, is a well-known effect that is established assuming the first-order a…
