Our prototype of a fully-functional Asynchronous Transfer Mode (ATM) switch validates the design of a 128 Gb/s optoelectronic ATM switch. Optoelectronics, rather than all optical componets, are used to simutaneously address all of the speci c requirements mandated by the ATM protocol. In this paper, we present the Illinois Pulsar-based Optical Interconnect (iPOINT) testbed, and present our resu...

The ingress and egress nodes in an all-optical network have an electronic inand egress part and an optical switch. This work analyses various architectures for interconnection of the "electronic" and "optical" parts of the network in order to tolerate single optical switch failures and single optical link failures. The architectures studied are: non-redundant (reference), fault tolerant optical...

This paper presents an architecture and implementation issues of an “almost-all” optical packet switch that does not rely on recirculating loops for storage implementation. The architecture is based on two rearrangeably nonblocking stages interconnected by optical delay lines with different amounts of delay. We investigate the probability of loss and the switch latency as a function of link uti...

This paper proposes a new switching architecture to be used in all optical packet switching networks. The proposed switch is derived from an original 2 × 2 two-stage multi-buffer switched delay line based optical switching node, known as an M-Quadro node. By incorporating bypass lines into the M-Quadro architecture and employing a novel switch control strategy, the optical packet switching node...

This paper presents a fast and large-scale optical circuitswitch architecture for intra-datacenter applications that uses a combination of space switches and wavelength-routing switches are utilized. A 1,440 × 1,440 optical switch is designed with a fast-tunable laser, 8 × 8 deliveryand-coupling switch, and a 180 × 180 wavelength-routing switch. We test the bit-error-ratio characteristics of al...

In this paper we discussed different switch architectures. We focus mainly on optical buffering. We investigate an all-optical buffer architecture comprising of cascaded stages of quantum-dot semiconductor optical amplifier-based tunable wavelength converters, at 160 Gb/s. We also propose the optical buffer with multi-wavelength converters based on quantum-dot semiconductor optical amplifiers. ...
