Dense wavelength division multiplexing (DWDM) networks that use expensive optical/electrical/optical (O/E/O) conversion at each end of a fiber link are called opaque networks. In an attempt to reduce the O/E/O conversion cost component, a combination of technological advances has been used. Improved optical amplifiers using distributed Raman amplification allow signals to traverse longer distan...

Optical network is a viable network for future communication, which transmits data at an average rate of 50Tb/s. Optical Burst Switching is a trusted mechanism used for Optical network. There is a good amount of research done in the area of security in Optical networks. In addition, the issues related to physical network security has been dealt with respect to Optical networks. Our proposed wor...

This article addresses the issues of scalable end-to-end QoS in Metropolitan DWDM networks serving as transit networks for IP access networks. DWDM o ering few wavelengths have in the past been deployed in backbone networks to upgrade point-to-point transmission where sharing is based on coarse granularity. This type of DWDM backbone networks o ering few lightpaths, provides no support for QoS ...

We experimentally demonstrated a 2×2 all-optical packet sorter which can be used as a building block for an N×N packet sorter for all-optical packet-switched network. Both the header and payload rates are 10 Gb/s. ©2008 Optical Society of America OCIS codes: (230.1150) All-optical devices; (060.4259) Networks, packet-switched; (060.1155) All-optical networks

Multicast applications such as multimedia, medical imaging, digital audio and video conferencing are bandwidth-intensive. With the advance in optical technology providing abundant bandwidth, it is natural to extend the multicast concept to optical networks in order to gain enhanced performance. This paper provides a comprehensive review of optical multicast techniques, covering the main optical...

Software-defined networking is finding its way into optical networks. Here, it promises a simplification and unification of network management for optical networks allowing automation of operational tasks despite the highly diverse and vendor-specific commercial systems and the complexity and analog nature of optical transmission. A fundamental component for software-defined optical networking ...

The most promising approaches for optical neural networks are based on intensity encoding However a serious drawback of intensity encoding is the lack of negative values and optical subtraction which are essential for rendering neural networks useful To overcome the need for optical subtraction a novel training method is described here that is es pecially useful for optical multilayer neural ne...

Abstract: This paper is concerned with the analysis of linear quantum optical networks. It provides a systematic approach to the construction a model for a given quantum network in terms of a system of quantum stochastic differential equations. This corresponds to a classical state space model. The linear quantum optical networks under consideration consist of interconnections between optical c...
