DESCRIPTION:Distinguished Lecture entitled "Metasurfaces: building blocks o
 f tomorrow’s optical technologies"\n\nAbstract:\n\nRecent advancements i
 n nanofabrications\, characterisations\, and computer modelling have allow
 ed the generation of arrays of engineered nanoparticles\, called meta-surf
 aces\, that extraordinarily control light characteristics. They can reprod
 uce the functions of bulky geometrical optics such as lenses\, mirrors or 
 filters. Alongside that\, occasionally\, metasurfaces can offer some funct
 ionalities\, such as tunability\, that are not achievable by geometrical o
 ptics. Such advances have led to revolutionary applications in several fie
 lds\, including but not limited to meta-lenses\, polarisation converters\,
  nano-sensors\, and holograms. In this talk\, I will briefly review the re
 search activities of the Advanced Optics and Photonics Group at Nottingham
  Trent University on light-matter manipulation for real-life applications.
  I will discuss how engineering metallic\, dielectric\, and semiconductor 
 nanoparticles enable us to control the light intensity\, frequency\, and p
 ropagation direction. I will demonstrate how such controls can help us to 
 generate optical nano-switches with switching time faster than the human e
 ye’s response. Also\, I will explain how we can engineer nanoparticles t
 o convert images from the near-infrared region\, invisible to human eyes\,
  to the visible region. Finally\, I will show our latest results on how na
 nostructures can help monitor individual proteins over time. These are a f
 ew examples\, among many other technologies that are being developed in th
 e community\, of why many people consider photonics at the heart of cuttin
 g-edge technologies in the 21st century.\n\nCo-sponsored by: University of
