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.

An efficient Fault Localization Algorithm for IP/WDM Networks

Patrick Thiran, Carmen Mas

We propose an algorithm for localizing multiple failures in an IP/WDM network. They can be either hard failures (unexpected events that interrupt suddenly the established channels) or soft failures (events that progressively degrade the quality of transmis ...

Thermal behaviour of miniaturized surface mounted devices

René Salathé, Reymond Clavel, Thomas Sidler

Considerable efforts are presently being made to improve miniaturization of optical devices and to achieve at the same time submicron assembly precision. Several groups are working on concepts based on passive alignment techniques (ex. integrated waveguide ...

Singlemode chalcogenide fiber infrared SNOM probes

Giorgio Margaritondo

We have fabricated and tested infrared scanning near-field optical microscope (IR-SNOM) probe tips made from singlemode chalcogenide fiber. The process used to create the tips was similar to conventional micropipette-puller techniques, with some modificati ...

Holographic data storage

Demetri Psaltis

Research into and the development of data storage devices is a race to keep up with the continuing demand for more capacity, more density, and faster readout rates. Improvements in conventional memory technologies-magnetic hard disk drives, optical disks, ...

First experimental results with the free electron laser coupled to a scanning near-field optical microscope

Giorgio Margaritondo

First experiments of coupling a free electron laser to a scanning near-field optical microscope (SNOM) are presented. To address the question of how important such spectroscopy can be for near-field infrared microscopy, we acquired images of the same regio ...

Holographic data storage in a DX-center material

Demetri Psaltis

We report on the optical storage of digital data in a semiconductor sample containing DX centers. The diffraction efficiency and the bit-error-rate performance of multiplexed data images are shown to agree well with a simple model of the material. Uniform ...

Programmable Image Associative Memory Using An Optical Disk And A Photorefractive Crystal

Demetri Psaltis

The optical disk is a computer-addressable binary storage medium with very high capacity. More than 1010 bits of information can be recorded on a 12-cm-diameter optical disk. The natural two-dimensional format of the data recorded on an optical disk makes ...
