Abstract:
 
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. The talk will discuss some experimental systems results achieved with key enabling reflective hybrid photonic integrated components operating at 10 Gb/s and 25 Gb/s for targeted optical access, metro transport, and datacenter interconnection network applications.
