COM•DTU is a world-leading research institute competing at the leading edge of optical communication research at the Technical University of Denmark, located in Kgs. Lyngby, approximately 15 km North-West of Copenhagen. COM•DTU’s research and education activities focus on telecommunications and optical technologies. Its five research groups cover areas as diverse as nanophotonics, fibre and nonlinear optics, optical transmission systems, networks and coding. At present time, approximately 125 researchers are employed at COM•DTU, including about 55 Ph.D. candidates. The mission of the Systems Competence Area, headed by Professor Dr. Techn. Palle Jeppesen, is to perform research and education in the field of high-speed optical communication systems at the highest international level. Its research activities are primarily concerned with optical signal generation, fibre transmission systems, and signal processing at all network levels, from the core to the access. Current research topics include optical time division multiplexing (OTDM) systems at bit rates up to 640 Gbit/s, optical modulation formats, especially multilevel phase and intensity modulation (DQPSK, D8PSK, ASK-DxPSK) at 10-40 Gbaud, optical packet and label switching, as well as technologies for fibre-to-the-home (FTTH) at the physical layer level. It maintains a state-of-the-art laboratory, including signal generation and detection at 10 and 40 Gbps, OTDM signal generation, multiplexing and demultiplexing up to 640 Gbps, bit error rate testing up to 50 Gbps, short pulse characterisation, transmission spans, WDM equipment, etc.
Personnel involved in EURO-FOS
Dr. Jorge Seoane received his Diploma of Telecommunication Engineering from the University of the Basque Country, Spain, in 2001, and his Ph. D. degree at COM•DTU in 2005. Since 2001, he has been involved in a number of EU supported projects: IST-METEOR aimed at developing terabit optical MANs; IST-TOPRATE searched a capacity increase in WDM transmissions system and investigated >640 Gb/s single-channel transmission capacity; IST-LASAGNE aimed at developing network subsystems using all-optical logic gates and optical flip-flops in all-optical label swapping (AOLS) networks. Finally, he collaborates within IST-GIBON, which addresses the challenges of very high bit rate opto-electronic transceivers suitable for 100 Giga Ethernet type applications.
Dr. Anders T. Clausen is currently head of the OTDM group within the System Competence Area at COM•DTU. He received his M.Sc. degree at the Institute for Electromagnetic Systems, now COM•DTU, in 1997. After graduation, he was technology assessor for the European ACTS project HIGHWAY, where he was involved in implementation and research of OTDM systems operating at 40, 80 and 160 Gbit/s, with special focus on demultiplexing, wavelength conversion, clock extraction and dispersion compensation. He has leaded COM•DTU’s contributions to the European IST project TOPRATE, where all aspects of ultra-high speed, to be exact 160 Gbit/s and beyond, OTDM systems are addressed, i.e. transmitter and receiver implementation combined with transmission aspects. His current research interests focus on OTDM communication systems with Tbit/s potential.
Dr. Idelfonso Tafur Monroy received his M.Sc. degree from the State University of Telecommunications, San Petersburg, Russia, in 1992, his Technical licentiate degree in Telecommunication from the Royal Institute of Technology (KTH), Stockholm, Sweden, in 1996, and his Ph. D. degree for the Eindhoven University of Technology, The Netherlands, in 1999. He has been involved in several EU founded research activities, both in the 5th (IST-STOLAS) and 6th (IST-MUFINS, IST-LASAGNE) framework programs, where he successfully shared technical advisory tasks with managerial responsibilities. His current research areas are the convergence at the physical layer between wireline and wireless communications, and the convergence of the optical metropolitan and access network interfaces with a view to bring broadband services directly to the end-user.
