We present the experimental demonstration of an all-optical demultiplexer for high speed OTDM data with optical regeneration capability. It is shown that higher order parametric interactions provide optical sampling with high extinction ratio. ...
In this paper we describe Graaasp, a social software currently under development to support the creation of a real usage database of social artifacts. Our goals are twofold: First to offer a generic aggregation service and user interface to people and comm ...
The article analyzes the influence of the Internet Protocol (IP) access interface on the packet loss probability and delay times in the optical packet switched network. The network and node model have been proposed, and the structure of the IP access inter ...
Continuously tunable, optically-controlled variable delay line based on dynamic Brillouin grating is exploited for automated synchronization of switching signals in a network node, enabling asynchronous contention resolution with packet priorization. ...
The AMIDA Automatic Content Linking Device (ACLD) is a just-in-time document retrieval system for meeting environments. The ACLD listens to a meeting and displays information about the documents from the group’s history that are most relevant to what is be ...
Circuit-switched backbone networks are appealing especially due to their low switching cost. However, some of their links may be poorly utilised with respect to the available capacity. Grooming can be used to improve this utilisation: optically switched li ...

The electrical consumption of the core global networks is becoming preoccupant. To reduce it, one may bet on technological advances improving the energetic profile of individual components. However, large energy savings can potentially already be achieved, ...

In this paper, an architecture for code-empowered optical CDMA (OCDMA) lightwave networks is presented. The architecture is based on reconfigurable optically transparent paths among users of the network to provide high-bandwidth optical connections on dema ...
Ultrasound imaging allows the evaluation of the degree of emergency of a patient. However, in many situations no experienced sonographer is available to perform such echography. To cope with this issue, the OTELO project “mObile Tele-Echography using an ul ...
This paper addresses the basic concepts of the packet switching in the optical domain and describes an analytical approach to evaluate the end-to-end performance of networks employing slotted (fixed length) optical packets. Thus, for a given topology and t ...
