Polarization-sensitive tunable extraordinary terahertz transmission based on a hybrid metal-vanadium dioxide metasurface
S. Hadi Badri, Sanam Saeidnahaei, Jong Su Kim
A thermally tunable extraordinary terahertz transmission in a hybrid metal-vanadium dioxide (VO2) metasurface is numerically demonstrated. The metasurface consists of a metal sheet…
Subwavelength grating waveguide filter based on cladding modulation with phase-change material grating
S. Hadi Badri, Saeid Gholami Farkoush
Subwavelength engineering and utilizing phase-change materials with large contrast in their optical properties have become powerful design tools for integrated silicon photonics. R…
High-Q Fano resonance in all-dielectric metasurfaces for molecular fingerprint detection
S. Hadi Badri, M. M. Gilarlue, Sanam Saeidnahaei +1
We present and numerically investigate a high-quality factor (high-Q) meta-atom with Fano resonance. Numerical simulations indicate that the designed meta-atom has a single sharp F…
Thermally reconfigurable extraordinary terahertz transmission using vanadium dioxide
S. Hadi Badri, Hadi Soofi, Sanam Saeidnahaei S
We numerically demonstrate a reconfigurable extraordinary terahertz transmission based on a phase-change material of vanadium dioxide (VO2). The proposed hybrid metasurface is comp…
33 Slot waveguide crossing based on Maxwell's fisheye lens
S. Hadi Badri, M. M. Gilarlue, H. Soofi +1
Intersection of two or more silicon slot waveguides is inevitable in modern optical integrated circuits based on silicon on insulator (SOI) platform. In this article, we design a M…
Polymer multimode waveguide bend based on a multilayered Eaton lens
S. Hadi Badri, H. Rasooli Saghai, Hadi Soofi
Reducing the bending radius of low-index contrast waveguides is essential in reducing the size of the integrated optical components. A polymeric multimode waveguide bend is present…
