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…
Narrowband-to-broadband switchable and polarization-insensitive terahertz metasurface absorber enabled by phase-change material
S. Hadi Badri, M. M. Gilarlue, Sanam SaeidNahaei +1
A terahertz absorber with controllable and switchable bandwidth and insensitive to polarization is of great interest. Here, we propose and demonstrate a metasurface absorber with s…
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…
Ultra-thin silicon-on-insulator waveguide bend based on truncated Eaton lens implemented by varying the guiding layer thickness
S. Hadi Badri, M. M. Gilarlue, S. G. Gavgani
Silicon-on-insulator (SOI) waveguides with different geometries have been employed to design various integrated optical components. Reducing the bending radius of the SOI waveguide…
