Alteration of superconductivity and radial breathing modes in suspended ropes of carbon nanotubes by organic polymer coatings

Meydi Ferrier, A.Yu. Kasumov, Vincent Agache, Lionel Buchaillot, Anne-Marie Bonnot, C. Naud, Vincent Bouchiat, Richard Deblock, Mathieu Kociak, Mathias Kobylko, Sophie Guéron, Helene Bouchiat

We have altered the superconductivity of a suspended rope of single walled carbon nanotubes, by coating it with organic polymers. Upon coating, the normal state resistance of the rope changes by less than 20%. But superconductivity, which on the bare rope shows up as a substantial resistance...

Surface electromagnetic waves in Fibonacci superlattices: theoretical and experimental results

Y. El Hassouani, H. Aynaou, E.H. El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, V.R. Velasco

We study theoretically and experimentally the existence and behavior of the localized surface modes in one-dimensional (1D) quasiperiodic photonic band gap structures. These structures are made of segments and loops arranged according to a Fibonacci sequence. The experiments are carried out by...

High crosstalk InP digital optical switch for microwave application

Malek Zegaoui, Joseph Harari, D. Lauvernier, Didier Decoster, Jean Chazelas

Because electro-optic switches are key elements for the synthesis of large bandwidth, high dynamic, true time delay optically controlled microwave antennas, we designed, fabricated and characterized a new digital optical switch grown on InP substrate, and based on carrier-induced effects. The...
