We demonstrate a scalable, energy-efficient, and pragmatic method for high-bandwidth wavelength multicasting using FWM in silicon photonic nanowires. We experimentally validate up to a sixteen-way multicast of 40-Gb/s NRZ data using spectral and temporal responses, and evaluate the resulting data integrity degradation using BER measurements and power(More)
The paper describes system and program metrics used for load balancing algorithms for Java program execution in the SOAJA (Service Oriented Adaptative Java Applications) executive environment. This environment aims in maintaining design and execution of large scale computing tasks in complex networked Grid environments. SOAJA services provide means for(More)
Look-ahead dynamic inter-processor connection reconfigura-tion is a multi-processor architectural model, which has been proposed to eliminate connection reconfiguration time overheads. It consists in preparing link connections in advance in parallel with program execution. An application program is partitioned into sections, which are executed using(More)
Electronically tunable optical true-time delay lines are proposed. The devices utilize the combination of apodised gratings and the free-carrier plasma effect to tune the enhanced delay of silicon waveguides at a fixed wavelength. Three variations of the proposed scheme are studied and compared. The compact and integrable devices can achieve tuning ranges(More)
The paper is concerned with a new distributed program design environment based on the global application states monitoring. The environment called PEGASUS (from Program Execution Governed by Asynchronous SUpervision of States) supplies to a programmer a ready to use control primitives to design distributed program execution control in which decisions for(More)
