Electric charge enhancements in carbon nanotubes: Theory and experiments

Zhao Wang, Mariusz Zdrojek, Thierry Melin, Michel Devel

We present a detailed study of the static enhancement effects of electric charges in micrometer-long single-walled carbon nanotubes, using theoretically an atomic charge-dipole model and experimentally electrostatic force microscopy. We demonstrate that nanotubes exhibit at their ends surprisingly…

Lamb wave attenuation in a rough plate. I. Analytical and experimental results in an anisotropic plate

Catherine Potel, Damien Leduc, Bruno Morvan, Claude L. Depollier, Anne-Christine Hladky, Jean-Louis Izbicki, Philippe Pareige, Michel Bruneau

The characterization of bounded roughened surfaces before applying adhesive joint, in order to detect poor cohesive and adhesive properties, remains difficult. Earlier studies based on analysis of surface wave (Rayleigh waves or Scholte waves) are not really adapted to the characterization of such…

Effects of raised-cosine pulse shaping on processing gain in acousto-optic correlators

O. Bazzi, Y. Mohanna, Fadi Khalil, Jamal Assaad

The effects of raised-cosine filtering on the processing gain of acousto-optic correlators (AOC) in direct-sequence spread-spectrum receivers are considered. For ideal AOCs, analytical expressions are derived for the full roll-off filter characteristics. The results are given in terms of the ratio…

Metal-metal terahertz quantum cascade laser with micro-transverse-electromagnetic-horn antenna

Wilfried Maineult, Pierre Gellie, Alessio Andronico, Pascal Filloux, Giuseppe Leo, Carlo Sirtori, Stefano Barbieri, Emilien Peytavit, Tahsin Akalin, Jean-Francois Lampin, Harvey E. Beere, David Ritchie

A 2.8 THz metal-metal quantum cascade laser operating with a microtransverse-electromagnetic-horn antenna has been demonstrated. By comparing the far-field radiation pattern to a standard ridge cavity with a cleaved facet, a striking improvement of the directionality is observed. The effectiveness…

Wide electrical tunability of a GaInAsP/InP microdisk resonator

Marie Lesecq, Sophie Maricot, Jean-Pierre Vilcot, Maxime Beaugeois

We report on the characterization of an InP⁄InGaAsP-material-based microdisk resonator optical filter. The originality here is constituted by the use of a localized control electrode that is used for the tuning of the resonance wavelength of the filter via the injection of a driving current. Tuning…
