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…

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…

Ultrafast acoustics in the middle UV range: coherent phonons at higher frequencies and in smaller objects

S. Ayrinhac, Arnaud Devos, A. Le Louarn, P.-A. Mante, P. Emery

We show that the propagation of coherent acoustic phonons generated by femtosecond optical excitation can be clearly resolved using a probe laser in the middle UV (MUV) range. The MUV probe is easily produced from a highrepetition- rate femtosecond laser and a homemade frequency tripler. We present…
