Fast and widely tunable optical packet switching scheme based on tunable laser and dual-pump four-wave mixing

Abstract: An optical packet switching scheme based on a fast electronically controllable tunable laser dual-pump four-wave mixing for wavelength conversion and an N/spl times/N arrayed waveguide grating for passive routing is examined. This scheme can realize ultrafast packet switching and large port switch fabrication, required in next-generation core optical packet routers. The performance is examined in terms of packet-based bit-error-rate measurements for packet-by-packet switching. Design issues are also discussed.

Photonic infrastructure for Grid enabled networks

Abstract: This work presents a novel solution towards a long-reach intelligent infrastructure for Grid networking. The proposed solution is based on the deployment of high capacity optical infrastructure whilst taking advantage of recent developments in optical networking technologies. Optical burst switching and a user network interface utilizing fast tunable optical technologies provide a physical infrastructure able to fulfill the Grid application requirements and make efficient use of network resources. Furthermore a control and management plane based on extensions of existing artifacts offers peer-to-peer distributed networking to enable Grid services.
