Isotropic gap formation, localization, and waveguiding in mesoscale Yukawa-potential amorphous structures
Murat Can Sarihan, Alperen Govdeli, Zhihao Lan +8
Amorphous photonic structures are mesoscopic optical structures described by electrical permittivity distributions with underlying spatial randomness. They offer a unique platform…
Electrical tuning of spin splitting in Bi-doped ZnO nanowires
Mehmet Aras, Çetin Kılıç
The effect of applying an external electric field on doping-induced spin-orbit splitting of the lowest conduction-band states in a bismuth-doped zinc oxide nanowire is studied by p…
Doping-induced spin-orbit splitting in Bi-doped ZnO nanowires
Mehmet Aras, Sümeyra Güler-Kılıç, Çetin Kılıç
Our predictions, based on density-functional calculations, reveal that surface doping of ZnO nanowires with Bi leads to a linear-in- splitting of the conduction-band states, thr…
Combined hybrid functional and DFT+ calculations for metal chalcogenides
Mehmet Aras, Çetin Kılıç
In the density-functional studies of materials with localized electronic states, the local/semilocal exchange-correlation functionals are often either combined with a Hubbard param…
Parametric Optomechanical Oscillations in Two-Dimensional Slot-Type High-Q Photonic Crystal Cavities
Jiangjun Zheng, Ying Li, Mehmet Sirin Aras +3
We experimentally demonstrate an optomechanical cavity based on an air-slot photonic crystal cavity with optical quality factor Qo=4.2\times10^4 and a small modal volume of 0.05 cu…
On-chip optical filters with designable characteristics based on an interferometer with embedded silicon photonic structures
S. Kocaman, M. S. Aras, N. C. Panoiu +2
We demonstrate chip-scale flat-top filters at near-infrared wavelengths using negative index photonic crystal based Mach Zehnder interferometers. Supported by full three-dimensiona…
