Current and past projects:

  • DFG project: New Horizons in Optical Networking with Elastic Spectrum Allocation and Parallel Transmission

In this project, we study a radically new paradigm in photonic network systems based on parallelism, defined as the system’s ability to dynamically break any serial data traffic into discrete parallel flows, and process each flow independently in either of the electronic or photonic domains, so it can best match application requirements, network traffic conditions and optical spectrum availability. It is precisely the combined and flexible parallelism in both layers, electronic and optical, and their cross-layer design at the lowest layers of the protocol stack, that makes our approach unique and potentially transformative.

Our research program seeks students as a part of our research team working on different topics in form of HiWi-Jobs, Master and Bachelor thesis.
