Dynamic hybrid metasurfaces
Sajjad Abdollahramezani, Omid Hemmatyar, Mohammad Taghinejad +10
Efficient hybrid plasmonic-photonic metasurfaces that simultaneously take advantage of the potential of both pure metallic and all-dielectric nanoantennas are identified as an emer…
Tunable nanophotonics enabled by chalcogenide phase-change materials
Sajjad Abdollahramezani, Omid Hemmatyar, Hossein Taghinejad +5
Nanophotonics has garnered intensive attention due to its unique capabilities in molding the flow of light in the subwavelength regime. Metasurfaces (MSs) and photonic integrated c…
Knowledge Discovery In Nanophotonics Using Geometric Deep Learning
Yashar Kiarashinejad, Mohammadreza Zandehshahvar, Sajjad Abdollahramezani +3
We present here a new approach for using the intelligence aspects of artificial intelligence for knowledge discovery rather than device optimization in electromagnetic (EM) nanostr…
Full color generation with Fano-type resonant HfO nanopillars designed by a deep-learning approach
Omid Hemmatyar, Sajjad Abdollahramezani, Yashar Kiarashinejad +2
In contrast to lossy plasmonic metasurfaces (MSs), wideband dielectric MSs comprising of subwavelength nanostructures supporting Mie resonances are of great interest in the visible…
