In this study we present the direct terahertz timedomain spectroscopic measurement of CVD-grown multilayer graphene (MLG) on PVC substrate with an electrically tunable Fermi level. In a configuration consisting MLG and injected organic dopant, the transmitted intensity loss of terahertz radiation was observed with an applied voltage between 0 and 3.5 V.We showed that MLG on PVC devices provided approximately 100 % modulation between 0.2 and 1.5 THz at preferentially low operation voltage of ca. 3V. The observed modulation bandwidth in terahertz frequencies appears to be instrument limited.

Graphene-enabled electrically controlled terahertz spatial light modulators
Kakenov, Nurbek; Takan, Taylan; ÖZKAN, VEDAT ALİ; Balci, Osman; Polat, Emre O.; Altan, Hakan; KOCABAŞ, COŞKUN (2015-05-01)
In this Letter, we demonstrate a broadband terahertz (THz) spatial light modulator using 5 x 5 arrays of large area graphene supercapacitors. Our approach relies on controlling spatial charge distribution on a passive matrix array of patterned graphene electrodes. By changing the voltage bias applied to the rows and columns, we were able to pattern the THz transmittance through the device with high modulation depth and low operation voltage. We anticipate that the simplicity of the device architecture with ...
Terahertz modulation using a bandpass filter combined with a Graphene Supercapacitor
Takan, Taylan; Nebioglu, Mehmet A.; Kakenov, Nurbek; Balci, Osman; KOCABAŞ, COŞKUN; Altan, Hakan (2015-09-22)
Graphene is proving to be an efficient medium for the control of mm-wave/THz radiation. Its electrical and dielectric properties allows it to be incorporated into various existing device architectures. One such application is in the modulation of the amplitude of the propagating THz radiation. Due to its electrical properties this interaction is typically broadband in nature. To make this frequency selective we propose the use of metamaterials or frequency selective surfaces. Generally, these structures per...
Applications in broadband THz spectroscopy towards material studies
Türkşen, Zeynep; Altan, Hakan; Department of Physics (2011)
The purpose of this work was to construct and analyze a THz time domain spectroscopy (THz-TDS) system by using a nanojoule energy per pulse ultrafast laser (non-amplified ultrafast laser or oscillator) source and a non-linear optical generation method for THz generation. First a THz-TDS system, which uses photoconductive antenna (PCA) method for THz generation, was built to understand the working principles of these types of systems. This THz-TDS system which used PCA for generation and a 2mm thick <110> Zn...
Quantum emitter interacting with graphene coating in the strong-coupling regime
Gunay, Mehmet; Karanikolas, Vasilios; ŞAHİN, RAMAZAN; Ovali, Rasim Volga; Bek, Alpan; TAŞGIN, MEHMET EMRE (2020-04-14)
We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are based on solutions of three-dimensional Maxwell equations, using a boundary element method approach. Interaction between the nanostructures produces sharp hybrid modes, even when the two are off-resonant. The coupling of the light to these "very sharp" plexcitonic resonances is an order of magnitude larger than its coupling to a quantum dot, and they are voltage tunable (continuously) in an 80-...
Tunable perfect metamaterial absorber design using the golden ratio and energy harvesting and sensor applications
ÜNAL, EMİN; Dincer, Furkan; TETİK, ERKAN; KARAASLAN, MUHARREM; Bakir, Mehmet; Sabah, Cumali (2015-12-01)
We present the design, characterization, theoretical and experimental verification of a tunable perfect metamaterial absorber (MA) based electromagnetic (EM) energy harvesting and sensor application. We have used the golden ratio while determining the dimensions allowing a simple configuration and an easy fabrication for the proposed structure. We have examined and analyzed the perfect absorption (both numerically and experimentally) and EM energy harvesting (numerically) behaviors of the proposed structure...
