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…

Graphene growth by molecular beam epitaxy on the carbon-face of SiC

E. Moreau, S. Godey, F.J. Ferrer, D. Vignaud, X. Wallart, J. Avila, M.C. Asensio, F. Bournel, J.J. Gallet

Graphene layers have been grown by molecular beam epitaxy (MBE) on the (0001¯) C-face of SiC and have been characterized by atomic force microscopy, low energy electron diffraction (LEED), and UV photoelectron spectroscopy. Contrary to the graphitization process, the step-terrace structure of SiC…

Microstub resonators based-waveguides for filtering and multiplexing devices

Yan Pennec, Bahram Djafari-Rouhani, Abdellatif Akjouj, Jerome O. Vasseur, A. Noual, L. Dobrzynski

In this chapter, we report numerical simulations, based on a two dimensions Finite Difference Time Domain (FDTD) method, of light propagation in two-dimensional semiconductor micro optical waveguides coupled to one or several lateral stubs. This resonator offers a filtering alternative to well-…

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…

A millimeter-wave inflatable frequency-agile elastomeric antenna

S. Hage-Ali, Nicolas Tiercelin, P. Coquet, R. Sauleau, Vladimir Preobrazhensky, Philippe Pernod

This letter reports a millimeter-wave frequency agile microstrip antenna printed on an ultrasoft elastomeric PDMS substrate. The microstrip patch antenna is supported by a PDMS membrane suspended over an air cavity. The distance H between the patch and the ground plane, and thus the resonant…
