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 propose and demonstrate the use of an adaptive membrane mirror to increase the efficiency of coupling light into optical single-mode fibers. The membrane mirror has an active area of 12 mm in diameter and is electrostatically activated by 37 electrodes. ...
Performance monitoring is one of the key features to create self-managed optical networks. Monitoring the characteristics of an optical channel is important for designing robust and reliable optical telecommunication system. This thesis examined the use of ...
We report, to our knowledge, the first active channel waveguide in Ti:sapphire. We have created [similar to] 1.4-μm high ribs in a [similar to] 10-μm thick Ti:sapphire planar waveguide by reactive ion etching. Following excitation by an Ar-ion laser, the r ...
We report here the fabrication of fiber chromatic dispersion compensators, along with the tests of those components in wavelength-division-multiplexed transmission at 10 Gb/s and an analysis of their performance by simulation. ...

We propose the use of standard multiwavelength Fabry–PÉrot (FP) lasers for distributed strain and temperature measurement in hybrid Raman- and Brillouin-based fiber-optic sensors. The multiple longitudinal modes of FP lasers allow for accurate spontaneous ...

The accurate mapping of chromatic-dispersion distribution along single-mode optical fibers with the best spatial resolution ever reported is experimentally demonstrated. The method consists of a new way of probing four-wave-mixing (FWM) efficiency along th ...
We describe a new method for performing simultaneous position-resolved measurements of chromatic dispersion and Brillouin shift along single-mode optical fibers. The technique provides consistent high-resolution and low-noise results for both quantities. O ...
We demonstrate the possibility of broadening the emissions spectra of superfluorescent fiber lasers by combinations of different kinds of single-mode doped silica fibers. We obtained an optical bandwidth of more than 70 nm (FWHM) between 1030 and 1100 nm u ...
A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...
A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as a transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM) and Space Division Multiplexing (SDM ...
