INFLUENCE OF PROCESSING PARAMETERS ON THE SCATTERING PROPERTIES OF FLUOROZIRCONATE GLASSES PREPARED BY THE GAS FILM LEVITATION TECHNIQUE

  • Baniel P.
  • Lopez A

Fluoride glasses for optical fibre applications were prepared using a containerless processing technique (the gas film levitation technique) to prevent the contamination of the glass melts by the crucible. Bulk glass samples of high optical quality were obtained by starting directly from a powder mixture of the different fluoride precursors. ...

GAS SOURCE MOLECULAR BEAM EPITAXY OF ALTERNATED TENSILE / COMPRESSIVE STRAINED GAINASP MULTIPLE QUANTUM WELLS EMITTING AT 1.5 MICRO-M

  • Emery J-Y
  • Goldstein L.
  • Starck C.

Compressive and tensile strained GaInAsP layers as well as zero-net strain multiple quantum wells, grown by gas source molecular beam epitaxy, have been investigated. Reflection high energy electron diffraction patterns show two-dimensional growth for compressive strained layers . Three-dimensional growth is observed after a few nanometers for tensile strained layers ...

MULTIUSER DETECTION FOR A MULTIMEDIA LEO SATELLITE SYSTEM

  • Durand C.
  • Durnez F
  • Sehier P.

This paper describes the optimisation of a class of multiuser detectors for a return link multimedia LEO satellites constellation system. We take into consideration the constraints of asynchronism over several chips and tight power control, which leads to consider both classes of parallel interference canceller (PIC) and multistage multiuser detectors. ...
