Silicon is increasingly considered as the next future platform for photonic integrated circuits. Low loss Si waveguides and in particular the microring resonator approach seems to be very promising toward the realization of ultra compact, low cost, multi-functionality integrated devices. A novel solution to achieve hit-less tunable add and drop filter on(More)
A novel approach to the automatic classiJcation of remote sensed images is proposed. This approach is based on a three-phase procedure: first pixels which belong to the areas of interest with large likelihood are selected as seeds; second the seeds are refined into connected shapes using two well known image processing techniques; third the results of the(More)
The enormous scale and complexity of data sets in functional neuroimaging makes it crucial to have well-designed and flexible software for image processing, modeling, and statistical analysis. At present, researchers must choose between general purpose scientific computing environments (e.g., Splus and Matlab), and specialized human brain mapping packages(More)
—A WDM-PON unbundling solution based on WDM/OTDM conversion is presented. It guarantees high bit-rate scalability, easy reconfigurability, modular unbundling, minimum number of fiber links, and " pay as you grow " strategy implementation. Each required subsystem is implemented exploiting nonlinearities in optical fiber with channel traffic rate at 10 Gb/s,(More)
It is widely recognized that in the new generation of photonic terabit packet routers optical integrated circuits will play a fundamental role for minimizing the cost of ownership, footprint, and power consumption of high-speed photonic interfaces. We review the present and future technologies for optical packet router architectures and the specific(More)
