All-optical switching based on a subwavelength metallic grating structure containing nonlinear optical materials has been proposed and numerically investigated. Metal-dielectric composite material is used in the switching for its larger third-order nonlinear susceptibility (approximately 10(-7)esu) and ultrafast response properties. The calculated dependence of the signal light intensity on the...

The Optical Burst Switching (OBS) is a technology positioned between optical circuit switching (OCS) and optical packet switching (OPS). It is a promising buffer-less DWDM switching technology that provides high wavelength utilization. One of the critical design issues in OBS network is effective planning in minimizing burst dropping resulted from resource contention. In this paper, we attempt ...

High performance packet switching networks are being deployed to provide sufficient data bandwidth for end users 3G services such as video streaming and broadband like data services. The use of high performance networks is, therefore, essential to the success of any 3G service. However, in practice, the deployment of High performance packet switching networks is hindered due to the improper con...

Resistive random access memory (ReRAM) has been considered the most promising next-generation nonvolatile memory. In recent years, the switching behavior has been widely reported, and understanding the switching mechanism can improve the stability and scalability of devices. We designed an innovative sample structure for in situ transmission electron microscopy (TEM) to observe the formation of...

The rapid development of Asynchronous Transfer Mode technology in the last 10-15 years has stimulated renewed interest in the design and analysis of switching systems, leading to new ideas for system designs and new insights into the performance and evaluation of such systems. As ATM moves closer to realizing the vision of ubiquitous broadband ISDN services, the design of switching systems take...

It is well known that the stability and performance of a networked control system (NCS) are strongly affected by the transmission delay, which is usually random in communication networks such as Ethernet. In order to cope with the random transmission delay and increase the control performance, a novel switching control approach for NCS is proposed. The random transmission delay is modelled by a...

The deployment of optical fibers as a transmission medium aroused the problem of speed mismatching between transmission and switching. To build a large IP router with capacity of 1 Tb/s and beyond, either electronic or optical switching can be used. Optical communications with photonic switching are promising to provide high bandwidth and low error probability. The major obstacle in this regard...
