Dynamics of optomechanical spatial solitons in dual-nanoweb structures
Dynamics of optomechanical spatial solitons dual-nanoweb structures Optics
2012/4/20
We theoretically investigate the stability and dynamics of self-channelled beams that form via nonlocal optomechanical interactions in dual-nanoweb microstructured fibers. These "optomechanicons" repr...
Optical Isolation Can Occur in Linear and Passive Silicon Photonic Structures
Optical Isolation Linear and Passive Silicon Photonic Structures Optics
2012/4/20
On-chip optical isolators play a key role in optical communications and computing based on silicon integrated photonic structures. Recently there have raised great attentions and hot controversies upo...
New resonant cavity-enhanced absorber structures for mid-infrared detector application
Optical resonant cavity Photodetectors HgCdTe Gratings
2012/4/19
A new dielectric Fabry-Perot cavity was designed for a resonant enhancing optical absorption by a thin absorber layer embedded into the cavity. In this cavity, the front mirror is a subwavelength grat...
Topological-phase effects and path-dependent interference in microwave structures with magnetic-dipolar-mode ferrite particles
Topological-phase effects path-dependent interference microwave structures magnetic-dipolar-mode ferrite particles

Different ways exist in optics to realize photons carrying nonzero orbital angular momentum. Such photons with rotating wave fronts are called twisted photons. In microwaves, twisted fields can be pro...
Abstract: We have fabricated ultra-luminescent samples with erbium-doped amorphous silicon sub-oxide (a-SiOx) layers deposited on SiO2/Si substrates. The layer thicknesses were designed to provide...
Broadband transmission properties of multilayered structures
Broadband transmission properties multilayered structures

The formalism of the scattering matrix is applied to describe the transmission properties of multilayered structures with deep variations of the refractive index and arbitrary arrangements of the laye...
Are there novel resonances in nanoplasmonic structures due to nonlocal response?
nanoplasmonic resonances nonlocal response
2011/9/13
We study the nonlocal response of a confined electron gas within the hydrodynamical Drude model.We address the question whether plasmonic nanostructures exhibit nonlocal resonances that have no counte...
Optical structures, algebraically special spacetimes, and the Goldberg-Sachs theorem in five dimensions
algebraically special spacetimes Goldberg-Sachs theorem
2010/12/20
Optical (or Robinson) structures are one generalisation of four-dimensional shearfree congruences of null geodesics to higher dimensions. They are Lorentzian analogues of complex and CR structures. In...
Photoluminescence Characterization of Al/Al2O3/InP MIS Structures passivated by anodic oxidation
Indium phosphide MIS structures Photoluminescence
2010/4/12
Metal-insulator-semiconductor (MIS) structures were produced by electron beam evaporation of Al2O3 on InP. Polyphosphate thin films of thickness 100-150 Å were used to passivate the interface In...
Butt-Coupling Loss of 0.1 dB/Interface in InP/InGaAs Multi-Quantum-Well Waveguide-Waveguide Structures grown by Selective Area Chemical Beam Epitaxy

The lateral coupling of waveguiding structures in both [011] and [0\bar{1}1] directions is studied using embedded selective area epitaxy by Chemical Beam Epitaxy. All growth steps are carried out unde...
Activity has many manifestations, from dark spots to bright regions, to the presence of the heated chromosphere, to the superheated corona. Sunspots are extended, strongly magnetic regions on the Sun....
