Strictly Non-Blocking Optical Cross - Connect for WDM Wavelength Path Networks

by P. S. André, J. L. Pinto, A. J. Teixeira, T. Almeida, A. Nolasco Pinto, F. Morgado, M. Pousa , 2001
"... We describe the design and performances of a strictly nonblocking optical cross-connect node for WDM wavelength path networks. The optical cross-connect (OXC) prototype was experimentally tested as an 2 x 2 WDM system with two input / output ports with two wavelengths per port. The OXC was inserted ..."

Survivable WDM mesh networks

by S. Ramamurthy, Laxman Sahasrabuddhe, Biswanath Mukherjee - Journal of Lightwave Technology , 1999
"... Abstract—In a wavelength-division-muliplexing (WDM) optical network, the failure of network elements (e.g., fiber links and cross connects) may cause the failure of several optical channels, thereby leading to large data losses. This study examines different approaches to protect a mesh-based WDM op ..."

On the Routing and Wavelength Assignment in Multifiber WDM Networks

by Mohamed Saad, Zhi-quan Luo - IN PROCEEDINGS OF GLOBECOM , 2002
"... This paper addresses the problem of routing and wavelength assignment (RWA) in multifiber WDM networks assuming neither a special topology nor wavelength converters. Given a traffic matrix, the number of fibers per link, and the number of wavelengths a fiber can support, we seek to realize the max ..."

Constructions and analyses of nonblocking wdm switches based on arrayed waveguide grating and limited wavelength conversion

by Hung Q. Ngo, Dazhen Pan, Chunming Qiao - IEEE/ACM Transactions on Networking , 2006
"... Abstract—Constructing fast wavelength division multiplexing switches with cheap, integratable components, less power con-sumption and noise accumulation, and low complexity is an important problem in optical networking. Typically, there are two request models widely considered. In one model, a conne ..."

not accumulate much noise, and are useful for both optical circuit-switching and optical packet/burst switching. As far as we know, these are the first of such constructions. Index Terms—Limited-range wavelength converters, non-blocking WDM cross-connects. I.

Wide-sense nonblocking WDM cross-connects

by Penny Haxell, April Rasala, Gordon Wilfong, Peter Winkler
"... A wavelength division multiplexed (WDM) network employs multiple wavelengths in order to carry many channels in an optical fiber. Switching is, ideally, done by a WDM cross-connect that allows each incoming input channel to be routed to any (unused) output channel. To do this the cross-connect requ ..."

Cascaded active silicon microresonator array cross-connect circuits for WDM networks-on-chip

by Andrew W. Poon, Fang Xu, Xianshu Luo - in Proc. SPIE , 2008
"... We propose a design of an optical switch on a silicon chip comprising a 5 × 5 array of cascaded waveguide-crossing-coupled microring resonator-based switches for photonic networks-on-chip applications. We adopt our recently demonstrated design of multimode-interference (MMI)-based wire waveguide cro ..."

We analyze the potential performance of the proposed photonic network in terms of (i) light path cross-connections

Design and Performance of Optical Cross-Connect Architectures With Converter Sharing

by Chai, Teck Yoong Chai, Tee Hiang Cheng, Gangxiang Shen, Sanjay K. Bose, Chao Lu - Design Studies , 2002
"... WDM techniques may be used to utilize the large bandwidth available with optical fibers. In the network context, this will allow lightpaths to be configured on demand between the various source-destination pairs using either wavelength-continuous or non-wavelength-continuous paths. Some degree ..."
