DESCRIPTION:Prof. Christophe Moser\, Laboratory of Applied Photonics Devic
 es LAPD\nAbstract:\nOptical imaging\, Additive manufacturing and Computing
  using light as the probing/energy source have been transformed in the las
 t decade and continue to be transformed by the “digitization” of light
 . The term “digitization” is intended to mean that there is more compu
 tational power available for computing as well as for driving optical devi
 ces such as high resolution spatial light modulators. The latter can dynam
 ically modulate the phase or amplitude of light beams with millions of dig
 itally addressable pixels\, a few micrometers in size.\nThis dynamical con
 trol of light beams is at the heart of new schemes of practical relevance 
 for optical imaging\, additive manufacturing and computing.\nSpecifically\
 , I will show our work on imaging for augmented reality and optical fiber 
 endoscopy where digitization allows to produce extremely small imaging foo
 tprint systems. In the field of additive manufacturing\, the digital contr
 ol of light has enabled us to pioneer a true 3D volumetric approach to pri
 nting that is a radical change to the traditional layered (2D+1) approach.
  This has led us to demonstrate ultra-fast fabrication time of centimeter 
 scale 3D printed object within seconds. This provides a path towards scala
 bility and near instant fabrication time in Additive manufacturing. Finall
 y\, I will show how digital light control and non-linearity in optical fib
 ers can be used to perform end to end machine learning tasks on par with t
 he best deep neural networks at a fraction of the energy.\n\nBio:\nChristo
 phe Moser started his career as an engineer at Hexagon Metrology in Switze
 rland after graduating from EPFL in physics in 1993. He was awarded a gran
 t from the Swiss Academy of Engineering Sciences to pursue research at the
  California Institute of Technology where he earned a doctorate degree in 
 2000 in optical information processing.\nChristophe co-founded and was the
  CEO of Ondax\, Inc. (acquired by Coherent) in Monrovia\, California. Ther
 e\, he has developed several commercially successful products based on vol
 ume holographic components such as tunable filters\, wavelength stabilized
  high power diode lasers\, pulse compressors and stretchers and Terahertz 
 Raman spectroscopy systems.\nIn 2010\, Christophe joined EPFL as an Associ
 ate Professor and is currently the Director of the MicroEngineering Sectio
 n.\nHis current research topics include light based volumetric additive ma
 nufacturing to reach micrometer resolution at the centimeter scale in diff
 erent materials whose properties ranges from very soft - hydrogels to very
  hard – ceramics\, glass. He is also interested in neuromorphic computin
 g using linear and non-linear propagation in optical fibers as computing e
 lements.\nHe has continued to be active in entrepreneurship by valorizing 
 research coming out of his laboratory.  In 2014\, he co-founded Composyt 
 Light Lab – augmented reality (acquired by Intel) as well as EarlySight\
 , Readily3D and Modendo in the last three years.
