AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We describe a technique for studying scattering from subwavelength features. A simple scatterometer was developed to measure the scattering from the single-submicrometer, subwavelength features generated with a focused ion beam system. A model that can des ...
We study the interaction of a mode propagating in a planar waveguide with a three dimensional rectangular defect (protrusion or notch) in the structure. The scattering by the defect disturbes the propagation of the mode and light is coupled out of the wave ...
We consider a design approach to reduce unwanted zero-order intensity due to profile depth error in diffractive elements. Our method is based on addition of local bias phase to a binary element phase, leading to the introduction of a third phase level. We ...
A stage-by-stage analysis of light propagation around a 90° corner in a two-dimensional photonic crystal waveguide was discussed. The coupling efficiency between the conventional ridge waveguide and the photonic crystal waveguide was quantified using a ser ...
We report waveguide-enhanced X-ray experiments on thin macromolecular films, such as spin-coated polymer films, self-assembled polyelectrolyte layers, and lipid membranes, prepared on solid surfaces. Upon the deposition of an additional thin inorganic (met ...
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 ...
We present practical and theoretical, stage-by-stage analysis of light propagation around a 90degrees corner in a two-dimensional photonic crystal waveguide. Using a series of different samples we quantify the coupling efficiency between the conventional r ...
Very high frequency oscillations of intense light fields interact with micron-size dielectric objects to exert dc optical forces that allow polarizable particles to levitate, to be trapped and to be bound. Such optical forces are also suitable to arrange c ...
Thermo-optical and electro-optical (plasma dispersion) effects for silicon based integrated optical modulators are becoming attractive and effective solutions for telecommunications applications such as switching for programmable optical add-drop multiplex ...
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 ...
