The DARPA CORONET program is laying the foundations for a next generation IP-over-optical network that supports 100 Tbps of traffic and provides rapid, on-demand, switched wavelength services. The wavelength services are very dynamic, with setup times of 100 ms and holding times as short as a few seconds to a minute. A major management challenge is designing a provisioning protocol for the dynamic...

We present a method for impairment-aware routing in transparent networks that allows constraint dependencies and objectives minimizing regeneration cost. The method is guaranteed to identify impairment-feasible paths when they exist and uses transponder resources efficiently.
The first successful hybrid integration of Si CMOS drivers with InGaAs-GaAs vertical cavity surface emitting (VCSE) laser arrays operating at bit rates up to 622 Mbit/s is described. This technology has potential for low cost, high-bandwidth communication links in optical interconnect and optical computing applications. The simple, power-efficient driver circuits were implemented in a standard 1.0...
The design, fabrication and characterisation of 1024-element matrix addressable vertical cavity surface emitting laser (VCSEL) arrays are described. A strained InGaAs quantum well VCSEL structure was grown by molecular beam epitaxy and an array of 32*32 lasers was defined using a proton implantation process. A matrix addressing architecture was employed, which enables the individual addressing of...
