DESCRIPTION:Prof. Luc Thévenaz\nAbstract\nJust over one generation\, opti
 cs has experienced a deep move\, enabling light to propagate complex infor
 mation and interact intimately with matter. I've been able to chart my car
 eer with a fresh eye\, free from the cumbersome legacy of classical optics
 \, and I'd like to share this path with you during this lesson\, which has
  taken us over some opened avenues. In particular\, the resonance of light
  with the medium vibrations has enabled us to discover amazing effects\, s
 uch as slowing down or speeding up the signal carried by light\, creating 
 optical memories or even sensors measuring temperature along the length of
  an optical fiber all over several tens of kilometers. The presentation wi
 ll conclude with some personal thoughts on the immeasurable difficulties e
 xperienced by researchers in gaining recognition for their visionary conce
 pts in the face of a wall of skepticism and conformism.\n \nThe presentat
 ion will take up the challenge of being intelligible to a cosmopolitan aud
 ience\, understanding either French or English.\n\n\nBiography\nFor more t
 han 30 years Prof. Luc Thévenaz has consistently made significant and fun
 damental contributions to fiber-optic sensing\, as well as to the research
  and implementations of slow and fast light in optical fibres. He has addr
 essed all aspects of the field from basic fundamental considerations throu
 gh sophisticated pioneering implementations. This technology has now enter
 ed the real world and contributes to make our world safer\, by anticipatin
 g catastrophic failures through the constant monitoring of large structure
 s and dangers subject to human and natural threats.\nHe also launched in t
 he mid-1990’s a pioneering activity in gas traces sensing based on spect
 roscopic techniques using near-IR and mid-IR semiconductor lasers. He has 
 realized extremely sensitive systems based on a photoacoustic detection pr
 inciple.\nHe is Fellow of the IEEE and Optica\, and Member of the Swiss Ac
 ademy of Technical Sciences.\n
