Fast and Sensitive Terahertz Detection in a Current-Driven Epitaxial-Graphene Asymmetric Dual-Grating-Gate FET Structure
Koichi Tamura, Chao Tang, Daichi Ogiura +7
We designed and fabricated an epitaxial-graphene-channel field-effect transistor (EG-FET) featured by the asymmetric dual-grating-gate (ADGG) structure working for a current-driven…
Nonlinear terahertz-wave radiation generated by mid-infrared dual-chirped optical parametric amplification femtosecond pulse laser excitation
Kyuki Shibuya, Kouji Nawata, Yoshiaki Nakajima +5
We demonstrate an efficient procedure for terahertz-wave radiation generation by applying a nonlinear wavelength conversion approach using a mid-infrared pump source. We used a 3.3…
Subwavelength and microstructured planar THz waveguides, theory and experiment
A. Markov, A. Mazhorova, B. Ung +4
Planar dielectric subwavelength waveguides are proposed as waveguides for THz radiation. The waveguide porous design maximizes the fraction of power guided in the air to avoid the…
Composite THz materials using aligned metallic and semiconductor microwires, experiments and interpretation
Anna Mazhorova, Jian Feng Gu, Alexandre Dupuis +8
We report fabrication method and THz characterization of composite films containing either aligned metallic (tin alloy) microwires or chalcogenide As2Se3 microwires. The microwire…
