Within the scope of our EU FP7 C3PO project, we are developing novel, energy-efficient, colourless photonic technologies for low-cost, next-generation dense wavelength-division-multiplexed metro transport and access networks. The colourless transmitters use reflective arrayed photonic integrated circuits, particularly hybrid reflective electroabsorption modulators, and multi-wavelength laser sources,...
A fully reconfigurable add/drop node for use in metro DWDM networks based on a novel switched reflective architecture is demonstrated. The scheme saves power and avoids the need for expensive tunable lasers on equipment cards.
We report progress towards low-power, colourless reflective photonic integrated circuits for cost-effective DWDM 100 Gb/s metro transport and 10 Gb/s access networks within the EU FP7 C3PO project.
This paper describes a novel, strictly non-blocking optical switch, scalable from a few wavelengths to hundreds of fibres worth of DWDM. The approach makes highly efficient use of low loss wavelength selective switches and couplers.
