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.
Few technologies have had as much impact on society as fiber optics. These tiny hair-sized glass wires have deeply transformed the way we access information, our modes of communication and even the behavior of consumers. Today, optical fibers are omniprese ...
A cw-244-nm-Ar+ laser was used to fabricate Bragg gratings in pristine and H-2-loaded Bi-Al-SiO2 optical fibers with index changes as high as 3.6 x 10(-4) and 19.3 x 10(-4), respectively. For comparison, fiber Bragg gratings in pristine and H-2-loaded SMF- ...
The Colladon symposium is a public event that will honor the physicist Jean-Daniel Colladon (1802-1890). He was a scientist born in Geneva and well known for his measurements of the speed of sound in the lake of Geneva, his development of tunnel drilling m ...
By imaging the angular spectrum of optical modes confined within subwavelength volumes, we investigate the impact of metallic and dielectric surrounding layers on the optical emission properties of planar silicon photonic crystal cavity. By scanning a mirr ...

Bragg gratings with reflectivity > 93% were fabricated in Bi-Al co-doped H-2-loaded optical fibers. Average index changes as high as +2.5x10(-3) were obtained. Positive core stress changes indicate a compaction contribution to the total index change. ...
The demand for capacity is growing exponentially with about 40-60% per year passing the installed network capacity. For the last two decades the transmission capacity per fiber has increased by more than three orders of magnitude: Single channel (wavelengt ...
We experimentally demonstrate that all-optical signal calculus can be realized based on dynamic Brillouin gratings in optical fibers. Temporal integration and first-order differentiation were performed for optical pulse with various waveforms. ...
The authors experimentally investigate the effects of atomic layer deposition (ALD) and laser-assisted oxidation on the optical modes in GaAs L3 photonic crystal air-bridge cavities, using layers of InAs quantum dots as internal light source. Four distinct ...
We address the concept of virtual transparency in optical fibres and its application to dynamic range extension in distributed sensors. A sensor featuring 100 km measurement range with 2 meter resolution is experimentally demonstrated. ...
A new type of all optical delay line is realized in fibers. A local dynamic grating reflector can be generated everywhere in the fiber, demonstrating >1 us delay for 650 ps pulses. ...
