Dual-service wireless LAN antenna-remoting system using uncooled directly modulated D'FB laser diodes

We report a fibre-optic wireless distribution system, which allows antenna-remoting of a dual-service IEEE 802.11b/g WLAN operating at 2.4GHz up to 700m over low-bandwidth 62.5/125μm MMF using highly linear uncooled directly modulated laser diodes. © 2004 Optical Society of America.

Nanostructured carbon films from supersonic cluster beam deposition: Structure and morphology

Nanostructured carbon thin films have been grown by deposition of cluster beams produced by a supersonic expansion. Due to separation effects typical of supersonic beams, films with different nanostructures can be grown by the simple intercepting of different regions of the cluster beam with a substrate. Films show a low-density porous structure, which has been characterized by Raman and Brillouin spectroscopy. Film morphology suggests that growth processes are similar to those occurring in a ballistic deposition regime.
