At the same time\, their direct int egration within active optoelectronic devices such as light emitters and p hotodetectors is far less established. In this talk\, I will report the de sign and development of plasmonic metasurfaces that can promote directiona l light emission and angle-sensitive photodetection from a nearby active m aterial. These results are significant for the continued miniaturization a nd large-scale integration of optoelectronic devices and related systems\, and as a way to create new functionalities and enable novel applications. Specifically\, the use of metasurface directional photodetectors for imag e sensing and processing will be presented\, including the demonstration o f lensless compound-eye vision with ultra-wide field of view\, optical edg e detection for computer vision\, and phase-contrast imaging.\n\nBiography : Roberto Paiella is a Professor of Electrical and Computer Engineering at Boston University with a joint appointment in the Division of Materials S cience and Engineering\, and a member of the BU Photonics Center. He recei ved his BS and MS degrees from Columbia University and his PhD from Caltec h. Prior to joining BU he worked as a postdoc at Bell Laboratories\, Lucen t Technologies. His research over the years has focused on the development and investigation of novel optoelectronic devices using bandgap engineeri ng\, plasmonics\, and nanophotonics. He has served on multiple professiona l committees\, including most recently as an editorial board member of Sci entific Reports and CLEO 2022 program chair.\n\nThe registraion site for i n-person attendance (including light meals\, free) is below.\n\nhttps://ww w.eventbrite.com/e/seminar-metasurface-enhanced-optoelectronics-by-prof-ro berto-paiella-bu-tickets-457176415967\n\nThe registration site for the onl ine (Zoom\, free) attendance is below.\n\n[https://us02web.zoom.us/webinar /register/WN_D1N0ob58TtuHAp8mD2S3cw](https://www.eventbrite.com/e/seminar- metasurface-enhanced-optoelectronics-by-prof-roberto-paiella-bu-tickets-45 7176415967)\n\nBldg: Hubble Auditorium\, Analog Devices\, Inc.\, Wilmingto n\, Massachusetts\, United States\, 01887\, Virtual: https://events.vtools .ieee.org/m/329763 LOCATION:Bldg: Hubble Auditorium\, Analog Devices\, Inc.\, Wilmington\, Mas sachusetts\, United States\, 01887\, Virtual: https://events.vtools.ieee.o rg/m/329763 ORGANIZER:keisukekojima@ieee.org SEQUENCE:6 SUMMARY:Metasurface-Enhanced Optoelectronics: Directional Light Emitters an d Computational Image Sensors URL;VALUE=URI:https://events.vtools.ieee.org/m/329763 X-ALT-DESC:Description: <br /><p><span class="bold">Abstract:&nbsp\;&nbsp\; </span>Plasmonic and dielectric metasurfaces have been widely investigated as a means to tailor the wavefronts of externally incident light for pass ive device applications.&nbsp\;&nbsp\;At the same time\, their direct inte gration within active optoelectronic devices such as light emitters and ph otodetectors is far less established.&nbsp\;&nbsp\;In this talk\, I will r eport the design and development of plasmonic metasurfaces that can promot e directional light emission and angle-sensitive photodetection from a nea rby active material.&nbsp\;&nbsp\;These results are significant for the co ntinued miniaturization and large-scale integration of optoelectronic devi ces and related systems\, and as a way to create new functionalities and e nable novel applications.&nbsp\;&nbsp\;Specifically\, the use of metasurfa ce directional photodetectors for image sensing and processing will be pre sented\, including the demonstration of lensless compound-eye vision with ultra-wide field of view\, optical edge detection for computer vision\, an d phase-contrast imaging.</p>\n<h6>&nbsp\;</h6>\n<p><span class="bold">Bio graphy:&nbsp\;&nbsp\;</span>Roberto Paiella is a Professor of Electrical a nd Computer Engineering at Boston University with a joint appointment in t he Division of Materials Science and Engineering\, and a member of the BU Photonics Center.&nbsp\;&nbsp\;He received his BS and MS degrees from Colu mbia University and his PhD from Caltech.&nbsp\;&nbsp\;Prior to joining BU he worked as a postdoc at Bell Laboratories\, Lucent Technologies.&nbsp\; &nbsp\;His research over the years has focused on the development and inve stigation of novel optoelectronic devices using bandgap engineering\, plas monics\, and nanophotonics.&nbsp\;&nbsp\;He has served on multiple profess ional committees\, including most recently as an editorial board member of Scientific Reports and CLEO 2022 program chair.&nbsp\;&nbsp\;</p>\n<p>The registraion site for in-person attendance (including light meals\, free) is below.</p>\n<p>&nbsp\; <a class="" href="https://www.eventbrite.com/e/s eminar-metasurface-enhanced-optoelectronics-by-prof-roberto-paiella-bu-tic kets-457176415967">https://www.eventbrite.com/e/seminar-metasurface-enhanc ed-optoelectronics-by-prof-roberto-paiella-bu-tickets-457176415967</a></p> \n<p>The registration site for the online (Zoom\, free) attendance is belo w.</p>\n<p>&nbsp\; <a href="https://www.eventbrite.com/e/seminar-metasurfa ce-enhanced-optoelectronics-by-prof-roberto-paiella-bu-tickets-45717641596 7">https://us02web.zoom.us/webinar/register/WN_D1N0ob58TtuHAp8mD2S3cw</a>< /p> END:VEVENT END:VCALENDAR
