Abstract: Existing models for inter-core crosstalk in uncoupled multi-core fibers neglect intra-core random polarization-mode coupling, and conjecture other mechanisms to justify experimental findings. In this work we show that random polarization-mode coupling can explain observed crosstalk values. Good agreement between theory and experiments is obtained.

Abstract: We demonstrate a highly-scalable distributed antenna system enabled by real-time bit-interleaved sigma-delta-over-fiber links. By (time-)interleaving multiple sigma-delta modulated in-phase and quadrature pairs into one bitstream for each fiber, the optical bit-rate efficiency is improved while the remote radio unit complexity remains low.

Mo3A-4: Keynote 3: Seeing the invisible – Optical Coherence Tomography in Medicine
Drexler, Wolfgang Drexler
Center for Medical Physics and Biomedical Engineering, Medical University Vienna (Austria)
Abstract: In the last 30 years optical coherence tomography (OCT) has established itself as a novel, unique non-invasive, optical medical diagnostic imaging modality, enabling unprecedented in vivo ‘visualization of the invisible’, i.e. the visualization of internal tissue structure in a variety of biological systems that cannot be seen with the naked eye. Imaging the eye has been the most successful and commercially most active medical field for OCT so far, but several other OCT applications, e.g. in the heart, internal organs, brain or skin are also extremely promising. In addition, improved versions of OCT and combination with other optical imaging techniques are under development that provide information about the function of tissue as well as molecular and chemical information of the investigated tissue which are on the verge of significantly improving diagnosis and therapy control in medicine.

Mo3A-3: Keynote 2: The dawn of quantum networks
Hanson, Ronald
QuTech and Kavli Institute of Nanoscience, Delft University of Technology (The Netherlands)
Abstract: Entanglement – the property that particles can share a single quantum state - is arguably the most counterintuitive yet potentially most powerful element in quantum theory. The non-local features of quantum theory are highlighted by the conflict between entanglement and local causality discovered by John Bell. Decades of Bell inequality tests, culminating in a series of loophole-free tests in 2015, have confirmed the non-locality of nature. Future quantum networks may harness these unique features of entanglement in a range of exciting applications, such as quantum computation and simulation, secure communication, enhanced metrology for astronomy and time-keeping as well as fundamental investigations. To fulfill these promises, a strong worldwide effort is ongoing to gain precise control over the full quantum dynamics of multi-particle nodes and to wire them up using quantum-photonic channels. Here I will introduce the field of quantum networks and discuss future plans and ongoing work with the specific target of realizing the first multi-node network wired by quantum entanglement, including first primitive network experiments using diamond-based quantum network nodes.
