DESCRIPTION:Join the IEEE Montréal Section and its' IEEE Photonics Society
  Chapter for a technical talk by Dr. Raphaël Pestourie\, PhD .\n\nIn phot
 onics\, fabrication technologies now enable us to build devices\, e.g. met
 asurfaces\, that have aperiodic patterns at the scale of the wavelength an
 d diameters of thousands of wavelengths\, which present an unprecedented o
 pportunity to shape light with complex objectives. However\, these devices
  are very challenging to simulate and even harder to optimize. This talk w
 ill present ways to harness the full computational power of modern large-s
 cale optimization in order to design metasurfaces by exploiting domain-dec
 omposition approximations and surrogate models. We will also present recen
 t experimental results of large-area lenses that are achromatic for severa
 l wavelengths across the visible. Finally\, we will present an efficient w
 ay to simulate and optimize collimators and concentrators for incoherent l
 ight using reciprocal simulations.\n\nCo-sponsored by: INRS\, STARaCom\n\n
