Topological Protection in Radiative Photonic Crystal Cavities

We study the signatures of topological light confinement in the leakage radiation of two-dimensional topological photonic crystal cavities that feature the quantum spin Hall effect at telecom wavelengths. The mode profiles in real and momentum space are retrieved using far field imaging and Fourier spectropolarimetry. We examine the scaling...

Experiences with MPTCP in an intercontinental OpenFlow network

The size and amount of e-science data sets is growing rapidly. Keeping up with the network demand in order to transfer these data sets over the Internet is a challenge. Single links do not have enough capacity anymore. Therefore we need to install more interfaces in the servers and use all available paths in the network. In this paper we...
