Optical seminar | 05 February 2021

The talk will review results on implementing structured light for experimental studies of Mie-type dielectric nanoresonators' optical response.

Nanophotonics over the years has grown from being just an area of research to unravel new physics to an avenue having opportunities in both novel phenomena and device applications. One distinctive feature of typical nanophotonic systems is that they operate on extremely low energy levels but still are robust enough to deal with dramatically high energy densities. The prospect of device applications however is tarnished due to energy losses via diffraction and material properties. The way around this roadblock is offered by active nanophotonics, which marries the concepts of engineering the efficiency of light trapping and those of light matter interaction (engineering gain media). This talk will highlight some of our research on active nanophotonics including works on nanoscale topological lasing and tunable mie resonant metasurfaces.
