Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Among all scattering processes, spontaneous Brillouin scattering originates from the interaction between light and thermal acoustic waves propagating in the medium. The interference resulting from the incident light and its spontaneously backscattered frac ...
We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept avoids expensive ...
This invention relates to a device for emitting addressable locations comprises parallel spaced-apart first conductors (10) intersecting with parallel spaced-apart second conductors (11). The intersecting first and second conductors define addressable loca ...
Several groups are presently investigating the opportunity to fabricate miniaturized optical devices characterized by high attachment precision. An automated surface mounted technique based on standardized supports of 10x10x4 mm(3) size and on active insit ...
Concerns the fabrication of miniaturized optical devices with height attachment precision. For active alignment of micro-optical elements machined with tolerances lower than the intended precision, an accurate 6-DOF robot is needed. This article describes ...
Considerable efforts are presently being made in the fabrication of miniaturized optical devices. An automated assembly technique for small optical components based on standardized holders and on-line alignment of the optical elements has been developed. T ...
Spectroscopic ellipsometry (SE) carried out at 300 K together with reflectivity measurements performed from 5 to 300 K are used to determine the temperature dependence of the refractive index of hexagonal GaN films between 360 and 600 nm. The refractive in ...
Characterization of the mechanical and thermal properties of the high aspect- ratio, negative, UV resist, SU-S has been carried out. This resist allows for a broad range of thicknesses to be obtained with a single spin process. Standard exposure with a UV ...
We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept: avoids expensive ...
The group index of well-defined cladding modes has been characterized for the first time to our knowledge by optical low-coherence reflectometry (OLCR) with a precision
