Warm Dense Matter (WDM) is a challenging science field, which is related to heavy ion inertial fusion and planetary science. It is difficult to expect the behavior because the state with high density and low temperature is completely different from ideal condition. The well-defined WDM generation is required to understand it. Moderate energy ion beams (∼ MeV/u) slightly above Bragg peak is an a...

A 640-Gb/s high-speed ATM switching system that is based on the technologies of advanced MCM-C, 0.25m CMOS, and optical wavelength-division-multiplexing (WDM) interconnection is fabricated for future broadband services. A 40-layer, 160 114 mm ceramic MCM forms the basic ATM switch module with 80-Gb/s throughput. It consists of an 8 advanced 0.25m CMOS LSIs and 32 I/O bipolar LSIs. The MCM has a...

Many researches have been investigated on planning or designing WDM networks assuming that the future traffic is known beforehand. Practically, it is difficult to predict the future traffic demand accurately since there are various types of data traffic with different traffic characteristics. In this thesis, we propose a scheme to design a WDM network that will accommodate as much traffic as po...

Wavelength-Division Multiplexing Michael Borella, Biswanath Mukherjee, Feiling Jia, S. Ramamurthy, Dhritiman Banerjee, and Jason Iness Department of Computer Science, University of California, Davis, CA 95616 Abstract Multiprocessor architectures based on optical interconnects employing wavelength division multiplexing (WDM) are considered. WDM is a technique used to divide the tremendous bandw...

WDM (wavelength division multiplexing) appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. It has the scalability problem with increasing the access node numbers in WDM ring architecture, so we further propose the alternatives of hierarchical WDM ring architecture. Since the traditional IP provides the best ef...

The performance of optical components such as photonic switch, OXC, Optical Amplifiers is degraded by the presence of Non-linear effects in Optical networks. Four-wave Mixing (FWM) is the main deteriorating factor in WDM (Wavelength Division Multiplexing) Optical Network. It is necessary to study the impact of FWM on the performance of WDM networks. In this paper, we study the effects of FWM al...

We present a novel optical metro node architecture that exploits the Wavelength Division Multiplexing (WDM) optical cross-connect nodes for interconnecting network elements, as well as computing and storage resources. The photonic WDM cross-connect node based on semiconductor optical amplifiers (SOA) allows switching data signals in wavelength, space, and time for fully exploiting statistical m...

R ECENT developments in wavelength division multi-plexing (WDM) technology have led to a tremendous amount of commercial and research interest in WDM-based networks. Until recently, WDM has been used primarily for point-to-point long haul transmission. However, with the emergence of WDM networking components, people are beginning to design and deploy WDM-based networks that take advantage of th...

In this paper, we investigate the problem of efficiently provisioning connections of different bandwidth granularities in a heterogeneous WDM mesh network through dynamic traffic-grooming schemes under traffic-engineering (TE) principles. Due to the huge amount of traffic a WDM backbone network can support and the large geographic area it can cover, constructing and upgrading such an optical WD...
