Highly-efficient broadband TE/TM polarization beam splitter
Kiyanoush Goudarzi, Doyoung Kim, Haewook Han
Highly-efficient broadband polarization beam splitters with small footprint and based on silicon photonics technology are of great importance in optical integrated circuits. In thi…
Inverse design of an all-dielectric digitized terahertz optical power splitter by particle swarm optimization method
Kiyanoush Goudarzi, Haewook Han
This letter proposes a 50:50 TE terahertz (THz) power splitter based on digitized metamaterials. The device is optimized using particle swarm optimization algorithm. The structure…
Ultra low loss broadband 1 2 optical power splitters with various splitting ratios
K. Goudarzi, S. Kim, I. Park +1
We designed Si-based all-dielectric 1 2 TE and TM power splitters with various splitting ratios and simulated them using the inverse design of adjoint and numerical 3D fin…
Ultra-High Normalized Bandwidth TE and TM Polarization Insensitive Terahertz Absorber with Graphene Disks Configuration
Omid Mohsen Daraei, Milad Rastkar Mirzaei, Kiyanoush Goudarzi +1
In this paper, we have proposed ultra-broadband terahertz absorber with three layers of periodic graphene disks arrays (PGDAs). A gold layer was utilized as backside reflector and…
