The feasibility of a survivable all-optical transport network over standard single-mode fibre between eight major European cities is investigated. The chosen topology is intended to ensure survivability after a link or a node failure. The maximum transmiss ...
We complemented with data taken in transmission mode the recently described tests of the novel spectromicroscope MEPHISTO (Microscope a Emission de Photoelectrons par Illumination Synchrotronique de type Onduleur). Transmitted x rays were converted by a ph ...
We develop a pseudospectral multi-domain formulation for the accurate modeling of generic diffractive optical elements, here exemplified by off-plane waveguide holograms for the coupling between guided waves and freely propagating wavefronts. The individua ...

The gyrotron system for ECH and burn control on ITER requires at least 50MW of RF power at frequencies near 170GHz operating in CW. To meet these requirements, high efficiency gyrotron tubes with greater than or equal to 1MW power output capability are nec ...
Dispersion supported transmission (DST) is a new technique which combines intensity modulation (IM) and optical frequency modulation (OFM) to allow transmission spans beyond the usual dispersion limit. Using computer simulation, DST limitations are evaluat ...

The in-situ growth of PbZrxTi1-xO3 (PZT) and PbTiO3 (PT) thin films by reactive sputter deposition has been investigated for applications with silicon substrates. In-situ deposition from three simultaneously operating magnetron sources was applied. At the ...
Raman scattering by coupled LO phonon-plasmon modes in p-type GaN layers has been measured for different hole densities up to 3 x 10(18) cm(-3) Both axial and planar coupled modes were clearly observed. The breakdown of usual selection rules for the planar ...
Experimental start-up results of a 118 GHz TE(22,6) gyrotron are presented and compared with theory. The theoretical excitation regimes of competing modes are computed in the energy-velocity-pitch-angle plane. The start-up paths through the plane are deter ...
In this paper, the authors further validate a theory presented previously by themselves for evaluating currents induced by external electromagnetic fields on a finite-length horizontal wire above a perfectly conducting ground. They present an approach to g ...
Experimental results of low-power excitation of a 118 GHz TE(22,6) rotating mode are presented. A rectangular waveguide is converted to a TE(22,6) circular waveguide mode using quasi-optical techniques. A good conversion efficiency is measured and the expe ...
