Photonic Technologies for Next-Generation Optical Transport Networks

Presenter: Caroline P. Lai, Postdoctoral Researcher,Tyndall National Institute, Ireland

We are witnessing an explosive growth in Internet traffic demand caused by broadband applications such as high-definition video streaming. Current network technologies cannot scale to meet these user-driven bandwidth demands with sustainable energy and cost. This is driving the need to redesign the optical transport network that forms the basis of the future Internet. Novel, energy-efficient optical network designs and photonic components will be imperative to support the rising bandwidth demands with low cost and reduced power consumption. In this talk, I will present two complementary designs that can effectively address these challenges. The first approach features a cross-layer optimized network, which uses optical switching and performance monitoring to create impairment-aware networks. The cross-layer framework allows optical packet transmission to be based on the physical-layer performance and higher-layer, quality-of-service parameters. Experimental demonstrations of the cross-layer platform show that packet protection switching techniques can be realized. The second approach uses reflective network architectures, which leverage multi-channel arrayed photonic integrated circuits with custom electronic circuitry.
