Mikael Title: Passive and tunable flat optics with dielectric nanoantennas Abstract: Dielectric nanoantennas and metasurfaces have recently emerged as a new nanophotonic platform paving way to new generation of flat optical components. They can control light at nanometer dimensions in an unprecedented fashion, not achievable by conventional bulk optics. This led to demonstrations of flat optics with extraordinary performance, e.g. very large numerical aperture or very large field of view. One of the existing challenges of metasurface-based flat optics is strong grating-like dispersion of metasurfaces, which typically limits their ability to perform high-quality imaging in a broad spectral range, e.g., with white light. In this talk, I will first show how combining a few large-field of view quadratic metalenses with image processing it is possible to achieve white-light wide-field-of-view imaging potentially applicable to regular smartphones or laptops. On the other hand, I will also demonstrate that the metasurface dispersion can be used in a constructive way to achieve hyperspectral imaging systems for space applications. I will then demonstrate that integrating these nanoantennas on top of actively controlled 1D and 2D electrode arrays embedded in liquid crystals it is possible to achieve fully controllable and dynamically switchable metasurfaces with a pixel size down to 1 micrometer. These metasurface-based spatial light modulators can generate arbitrary wavefront patterns and can be used for beam steering in LiDAR devices or tunable holography in 3D holographic displays. Bio: Arseniy Kuznetsov received his double PhD degree from University Paris 13 (France) in 2005 and from Institute of Applied Physics RAS (Russia) in 2006. Since 2007 till 2011 he worked at the Laser Zentrum Hannover (Germany) as Humboldt Research Fellow. Since October 2011 till now he has been working in A*STAR, Singapore first in the Data Storage Institute and now in the Institute of Materials Research and Engineering. He is currently appointed as Senior Principal Scientist II, Director of Nanoantenna-SLM and Nanoantenna-LED Programs and Head of Advanced Optical Technologies Department. Current activities of his group are devoted to development of novel nanodevices based on dielectric nanoantennas and metasurfaces. He is an author of >90 journal papers (incl. Science, Nature Nanotechnology etc.) and a co-inventor of >20 filed patent applications. For his pioneering research on optically resonant dielectric nanostructures and dielectric nanoantennas, he was awarded 2016 IET A F Harvey Engineering Research Prize, 2017 NRF Investigatorship Award and 2020 IPS World Scientific Physics Research Medal and Prize. In 2020 he was also elected to be an Optica Fellow and in 2023 an A*STAR Fellow.

It may be possible to register for the program later if there still are seats left. The subject is a new one and presently a "hot" one so take a chance to get an introduction to it. The pioneer of the field, Prof Pablo Jarillo-Herrero will give the 2023 Gothenburg Mesoscopic Lecture, sponsored by the Nobel Institute of Physics, see attached poster. It will be a review giving hints of the future and possible application. I know that he gives excellent talks. The European expertise will contribute to the symposium, described below. Welcome! Pablo Jarillo-Herrero v?ckte stort uppseende p? APS marsm?te f?r fem ?r sedan d? han visade att tv? grafenskikt, p? varandra med en magisk vinkel av 1.08 grader mellan skikten, blev ledande och rentav supraledande med uppf?rande liknande h?gtemperatursupraledande kuprater och vars karakteristiska dom av ?verg?ngstemperatur mot dopning kunde styras med hj?lp av f?lt. Detta ledde till stor aktivitet inom ?moir? matter?, inte bara grafen utan med flera andra 2D skikt. Flera ordnade system som ferromagnetism, ferroelektricitet, funktionella isolatorer och halvledare upptr?der ocks? i dessa ?verstrukturer med extremt flata energiband. Intressanta till?mpningar kan realiseras inom omr?det, som ben?mns ?twistronics?. Pablo J-H gav en fullsp?ckad ?versikt, som Kavlif?rel?sning, vid ?rets APS marsm?te. Vi har lyckats f? honom att bli ?rets Gothenburg Mesoscopic Lecturer den femte oktober i ?r. Dessutom ?r flera av Europas mest k?nda forskare inom twistronics inbjudna till ett minisymposium som ges 5-6 oktober, varvat med inhemska bidrag av framst?ende forskare. Passa p? att deltaga. ?n finns ett tjugotal platser kvar. Se 2D materials and devices, twisted layers incl. Gothenburg Mesoscopic Lecture f?r program och registrering (engelska versionen). Du m?ste anm?la om du inte vill deltaga i buff?-middag 5/10 och/eller ha en lunchsm?rg?s. Det ?r en stor utgift och du blir inte popul?r, om du inte anm?ler. Du ?r v?lkommen, det finns n?gra platser kvar. Man beh?ver inte deltaga i hela programmet. Pablo Jarillo-Herrero will give the 2023 Gothenburg Mesoscopic Lecture, sponsored by the Nobel Institute of Physics. It will be an introduction to a symposium, arranged together with the Area of Advance, Nano at Chalmers concerning properties and applications of 2D electron gases, particularly Moir? matter. Several international and national researchers will give reviews and details of a fashionable and fascinating field of research. More information and register at 2D materials and devices, twisted layers incl. Gothenburg Mesoscopic Lecture Note that you have to tell if you do not want to have dinner with speakers Oct 5 and/or a lunch baguette Oct 6. They are costly and you are not popular if you do not cancel. Welcome to the symposium, there are still seats available at Kollektorn. You do not need to participate in the whole event. Tord Claeson Samuel Lara Avila Eva Olsson It is not possible to load up the poster on Mesoscopic Physics, it will be sent as soon as the system allows. -------------- next part -------------- An HTML attachment was scrubbed...
