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...

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...

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...
