DESCRIPTION:Paula Nuño Ruano\nThe EPFL Photonics Chapter (EPC) is very 
 pleased to announce and cordially invite you to our monthly ‘Pizza-Opti
 cs-Beer’ (POB) seminar on February 19th\, at 18:15 in room DIA 00
 3. \n\nThis month we will have the pleasure to host Paula Nuño Ruano -
  postdoctoral researcher in the Photonic Systems Laboratory (PHOSL) with t
 he presentation entitled:\n\n"Silicon subwavelength devices for efficient 
 Brillouin scattering"\n\nThe talk will be followed by the General Assemb
 ly of our association\, and the apéro (pizza&beer).\n\nFor organizationa
 l purposes (if you want to eat pizza!)\, please confirm your participatio
 n using this Doodle.\nDon’t hesitate to extend the invitation to any c
 olleague!\n\nHope to see you there\,\nThe team of the EPFL Photonics Chapt
 er\n\n\n\nAbstract:\nSilicon photonics attracts immense interest in fundam
 ental research and technological and commercial development in a wide vari
 ety of fields\, such as on-chip signal processing\, sensing\, on-chip to f
 ree-space communications\, and even quantum information and computing. In 
 this context\, Brillouin scattering emerges as a promising tool for the ne
 xt generation of integrated circuits. This nonlinear interaction between l
 ight and mechanical modes of a structure couples optical photons (in the T
 Hz regime) with MHz- and GHz-phonons\, allowing a very efficient frequency
  conversion. This property is critical for microwave signal processing and
  quantum transduction between superconducting qubits and optical fibres\, 
 for instance. Novel integrated designs yielding strong optomechanical coup
 ling have been an active research field since the early 2000s. Due to thei
 r small size\, tight light confinement\, and large optical interaction wit
 h the structure boundaries\, these new geometries promise an exceptional o
 ptomechanical response. In this talk\, I present some of our results on su
 bwavelength engineering for enhancing Brillouin scattering in silicon dev
 ices. Subwavelength structures\, i.e.\, periodic geometries with a pitch s
 maller than half the optical wavelength\, offer unique control of light pr
 opagation\, anisotropy\, and optical mode engineering. Thanks to recent de
 velopments in fabrication facilities\, these structures promise a new gene
 ration of silicon-on-insulator compact devices with novel capabilities wit
 hout incorporating new materials. I will show how these devices offer new 
 solutions to some of the main challenges of the field. \n\n\n\nYou don't 
 know POBs?\nPOBs (Pizza-Optics-Beer) are monthly seminars organized by the
  student association EPFL Photonics Chapter.\nA PhD or a postdoc gives a 2
 0-minutes presentation about his/her research in photonics. Discussions co
 ntinue informally around pizza and beers!\nThe event is free and open to a
 nyone.\n\n\nJoin us at General Assembly!\nThe General Assembly is ope
 n to everyone. Joining EPC as a committee member is a great chance to have
  closer connections to your peers in academia and industry. As a member\, 
 you will have funding to invite speakers from around the world and organiz
 e social activities. You may also benefit from travel grants and registrat
 ion fee waivers. \n\nWe thank the Doctoral Program in Photonics (EPDO)\, 
 the Society of Photo-Optical Instrumentation Engineers (SPIE.)\, Optica
  and SwissPhotonics for their support.
