Wedge-type negative index metamaterial at 0.5 THz

Eric Lheurette, Frédéric Garet, Shengxiang Wang, Karine Blary, Jean-Louis Coutaz, Didier Lippens

Negative refraction through a fishnet related metamaterial is demonstrated at 0.5 THz. This characterization is based on refraction angle determination through a prism-like structure. The measurements are performed by means of a goniometric time-domain spectroscopy system while a numerical…

Ab initio calculation of the binding energy of impurities in semiconductors : application to Si nanowires

Y.M. Niquet, L. Genovese, C. Delerue, T. Deutsch

We discuss the binding energy Eb of impurities in semiconductors within density functional theory (DFT) and the GW approximation, focusing on donors in nanowires as an example. We show that DFT succeeds in the calculation of Eb from the Kohn-Sham (KS) hamiltonian of the ionized impurity, but fails…

Experimental verification of negative refraction for a wedge-type negative index metamaterial operating at terahertz

Shengxiang Wang, Frédéric Garet, Karine Blary, Eric Lheurette, Jean-Louis Coutaz, Didier Lippens

We report on angle-resolved time domain spectroscopy (TDS) carried out on a prismlike negative index metamaterial operating around 0.5 THz. The wedge-type devices are constituted of hole arrays etched in gold thin films, which are stacked according to a sequential mask shift. By means of a…

Microwave modulation of terahertz quantum cascade lasers : a transmission-line approach

Wilfried Maineult, Lu Ding, Pierre Gellie, Pascal Filloux, Carlo Sirtori, Stefano Barbieri, Tahsin Akalin, Jean-Francois Lampin, Isabelle Sagnes, Harvey E. Beere, David Ritchie

We report on microwave impedance measurements of metal-metal ridge-waveguide terahertz quantum cascade lasers. Experimental data, recorded at 4 K in the 100 MHz–55 GHz range, are well reproduced by distributed-parameter transmission-line simulations, showing that the modulation cutoff is limited by…
