DTU
Technical University of Denmark
DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increase and develop our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
The Department of Photonics Engineering participates in a large number of EU programmes as partner or coordinator. Within integrated optics, the core competences include micro/nano fabrication, ultrafast optical signal processing, high speed optical systems, nonlinear optics etc. DTU Fotonik won the Horizon 2020 "Breaking the optical transmission barriers prize" with the PHOTONMAP proposal.
In the project SiComb, DTU is going to design, fabricate and characterize SiC waveguide devices.
DTU has the most advanced cleanroom facilities for nanofabrication at Nordic countries. These nanofabrication facilities consist of e-beam writer, nanoimprint and deep-UV stepper. The combination of these tools enables DTU active in areas of both research and innovation.
Our team
Haiyan Ou
Haiyan Ou PhD in 2000, associate professor since 2005. Her research interest is primarily in semiconductors materials and devices for integrated optics, photovoltaics and light emission. She developed her scientific career at Institute of Semiconductors of Chinese Academy of Sciences and DTU Fotonik. She has been working on integrated optics for 22 years being especially involved in several research activities and projects on building blocks for integrated optics, silica-on-silicon arrayed waveguide gratings, nonlinear integrated waveguides, silicon photonics for optical communications, innovative solution for next generation communication infrastructure etc. She is a PI/WP leader in LEDSiC (a new type of white light-emitting diode using fluorescent silicon carbide), NORLED (Nordic light-emitting diode initiative). It is her first time to participate FET project.
Karsten Rottwitt
Karsten Rottwitt PhD in 1993 from Technical University of Denmark, employed at DTU Fotonik in 2002, full professor since 2011, has more than 125 peer-reviewed international journal papers and more than 130 international conference contributions and 11 patent-families. Member of Editorial board OPTICA (2014-2020) and in 2019 appointed senior member OSA. His research interests are focused on nonlinear effects in optical fibers, fundamental aspects as well as applications. His main contributions are within Raman scattering in optical fibers and four-wave mixing. He is currently project coordinator and PI of an EU project within the QUANTERA programme.He has co-authored one graduate level text book on nonlinear optics.
Paul Michael Petersen
Paul Michael Petersen Ph.D. degree in physics from the Technical University of Denmark. Since 2011 he has been full professor in Optics. He has more than 20 years of research experience in laser physics, nonlinear optics, and biomedical optics and he has headed several collaborative research projects within laser physics. He is the author of the university textbook “Nonlinear Optics” and the white book “Optics in Denmark” (published in 1996). Until 1989 he worked in the fields of optical chaos and nonlinear optics in semiconductors. In 1994 he joined the Optics and Fluid Department at Risø National Laboratory. From 2001 until 2007 he was head of Laser Systems and Optical Materials at Risø National Laboratory. In the period 2002-2012 he was adjunct professor in Optics at the Niels Bohr Institute, Copenhagen University.
