The local interference method (LIME) is introduced as a tool for simulating guided mode excitation by finite gratings in monomode waveguides. This efficient and versatile calculation scheme considers each grating line as a scattering center radiating into ...
X-ray waveguides offer a novel approach for nanobeam production, which may become useful in coherent beam imaging and phase contrast projection microscopy. Internal field enhancement, coherency properties, and coupling efficiency of these devices have been ...
We present a new technique for computing the electromagnetic field that propagates and is scattered in three-dimensional structures formed by bodies embedded in a stratified background. This fully vectorial technique is based on the Green's tensor associat ...
We experimentally and theoretically study the controlled coupling between localized and delocalized surface plasmon modes supported by a multilayer metallic photonic crystal slab. The model system to visualize the interaction phenomena consists of a gold n ...
Some 15 years ago, optical topographic signals with subwavelength resolution were obtained independently by several experimental teams. Since this exploratory period, a growing number of experimental configurations have been proposed and continuously devel ...
The in-coupling process for grating-coupled planar optical waveguide sensors is investigated in the case of TE waves. A simple analytical model based on the Rayleigh-Fourier-Kiselev method is applied to take into account the depth of the grating coupler, w ...
The design, fabrication and characterization of CMOS-compatible optoelectronic devices is discussed. All devices are fabricated on silicon on insulator (SOI) substrates which makes them suitable for three-dimensional (3-D) telecommunication photonic integr ...
