Left-handed dispersion of a stack of sub-wavelength hole metal array et terahertz frequencies

Charles Croënne, F. Garet, Eric Lheurette, J.-L. Coutaz, D. Lippens

We report on the electromagnetic response of a stack of subwavelength hole metal arrays. The samples were designed for exhibiting left handed dispersion branches under normal incidence, and their transmissivities were optimized via the fabrication of elliptical-shaped holes. They are constituted of…

A High Mobility Field-Effect Transistor as an Antenna for sub-THz Radiation

Maciej Sakowicz, Jerzy Łusakowski, Krzysztof Karpierz, Marian Grynberg, Wojciech Gwarek, Stephane Boubanga Tombet, Dominique Coquillat, Wojciech Knap, Andrey Shchepetov, S. Bollaert

The experiments on radiation coupling to field effect transistors working as terahertz radiation detectors are reported. Two types of high electron mobility transistors: InGaAs/InAlAs and GaAs/AlGaAs, with different layout geometries are studied. We show that terahertz radiation coupling efficiency…

Recent developments of an opto-electronic THz spectrometer for high-resolution spectroscopy

Francis Hindle, Chun Yang, Gaël Mouret, Arnaud Cuisset, Robin Bocquet, Jean-Francois Lampin, Karine Blary, Emilien Peytavit, Tahsin Akalin, Guillaume Ducournau

A review is provided of sources and detectors that can be employed in the THz range before the description of an opto-electronic source of monochromatic THz radiation. The realized spectrometer has been applied to gas phase spectroscopy. Air-broadening coefficients of HCN are determined and the…
