THz Probe Studies of MBE Grown Epitaxial GaAs
Koseoglu, D.; Gullu, H. H.; Altan, Hakan (2009-08-28)
We have built a THz time-domain spectrometer driven by a sub-15fs pulse duration mode-locked Ti:Al203 laser. Using THz time-domain spectroscopy with photoconductive antenna for THz generation and electro-optic sampling for detection as well as photoexcited THz spectroscopy, we measured the carrier concentrations and mobilities of epitaxially grown undoped GaAs samples to be used in photoconductive antenna production. The samples were grown at 600 °C to 1 μm effective layer thickness on top of a 650 μm SI-Ga...

THz characterization of a metamaterial-based Spatial Light Modulator
Chikhi, N.; Lisitskiy, M.; Casini, R.; Papari, G. P.; Tkachenko, V.; Altan, Hakan; Andreone, A. (2014-05-09)
The aim of this work is to investigate new classes of artificial materials exhibiting unconventional properties in order to build novel devices operating in the Terahertz regime. We focus on the design, fabrication and characterization of tunable metamaterials with unit cells based on Split Ring Resonators. By incorporation of a nematic liquid crystal in the structure, we observe a frequency shift in the resonant response over 10% in bandwidth and more than 10 dB change in the signal absorption. We discuss ...
THz transmission and detection through glow discharge detectors
Cinar, K.; Altan, Hakan; Sahin, A. B. (2013-04-30)
The capability of low cost glow discharge detectors (GDDs) to detect terahertz (THz) radiation has drawn much attention recently. In order to employ them in applications such as THz imaging these studies have typically focused on the response of the GDD at specific frequencies. To better understand the spectral behavior of glow discharges, we have not only examined the response of the GDD at a specific frequency of 118 GHz, but also we examined the interaction mechanism of GDDs with THz radiation using tera...
