in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

Photonic packet switches can offer high data rates and format transparency as required by future communication system. Although electronic technology can achieve high switching speed, it is not compatible with the transmission bandwidths of the fiber-optic links. This paper is concerned with alloptical time division multiplexing router based on all-optical switching device. Three terahertz opti...

Tratflc Matrlx AbstractA detailed analytical traffic model for alloptical wavelength division multiplexing (WDM) photonic packet switched networks is presented and the requirements for buffer size, and link dimensions are analyzed. This paper shows that due to the topology, packets may generate traffic bottlenecks produced by a tendency of the routing scheme to send packets with different desti...

The IST-LASAGNE project aims at designing and implementing the first, modular, scalable and truly alloptical photonic router capable of operating at 40 Gb/s.

Abstrac: We present simulation results of an ultrafast alloptical interferometric switching devices based upon the resonant nonlinearity in a semiconductor optical amplifier (SOA). We have investigated two configurations: one based upon a Sagnac interferometer and one based upon a MachZehnder interferometer. The switches have been used to model a 1x2 all-optical OTDM router. Simulation results ...

Introduction The optical-label switching (OLS) technology supports transparent all-optical routing and sophisticated network functions by processing the short label in the electronic domain while leaving the data payload in the all-optical domain [1]. In this way, the routing is independent of the payload data format and bit rate. Moreover, with the help of electronic circuit, the router can su...

This paper discusses multi-hop operation of an optical-label switching system, demonstrating rapid alloptical packet switching with 2R regeneration for the data and optical label swapping for the label. Introduction Optical-label switching technology has the potential to provide low latency and transparency desired for the next generation Internet [1-2]. For network applications, the router mus...

This paper discusses optical-label switching and an experimental demonstration of high-speed all-optical packet switching with all-optical label-swapping capabilities. The subcarrier optical-label content was optically extracted and compared against the forwarding table, which induced packet forwarding as well as label-swapping decisions. The alloptical label processing technique was immune fro...

Ultrafast processing of packets is demonstrated and the performance analyzed for the off-ramp portion of an alloptical access node. The off-ramp consists of synchronized fiber lasers driving an all-optical header processor that includes nonlinear optical loop mirrors (NOLM), electrooptic router, and demultiplexer in the form of a two-wavelength NOLM. We achieve switching contrasts of 1O:l for t...
