Enhanced Meta-Displays Using Advanced Phase-Change Materials
Omid Hemmatyar, Sajjad Abdollahramezani, Ioannis Zeimpekis +12
Structural colors generated due to light scattering from static all-dielectric metasurfaces have successfully enabled high-resolution, high-saturation, and wide-gamut color printin…
Advanced Phase-Change Materials for Enhanced Meta-Displays
Omid Hemmatyar, Sajjad Abdollahramezani, Sergey Lepeshov +4
Structural colors generated due to light scattering from static all-dielectric metasurfaces have successfully enabled high-resolution, high-saturation and wide-gamut color printing…
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…
Meta-optics for spatial optical analog computing
Sajjad Abdollahramezani, Omid Hemmatyar, Ali Adibi
Rapidly growing demands for high-performance computing, powerful data processing systems, and big data necessitate the advent of novel optical devices to perform demanding computin…
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…
Wide-Band/Angle Blazed Dual Mode Metallic Groove Gratings
Omid Hemmatyar, Mohammad Ali Abbassi, Babak Rahmani +2
We introduce a new and simple approach to acquire wide-band/angle blazing operation in one-dimensional metallic gratings supported by equivalent circuit analysis. The gratings that…
