PhD scholarship in Optical Communications (Denmark)

DTU Fotonik works with all areas of photonic engineering, including a strong focus on optical communications.

Responsibilities and tasks
This position is for a PhD study focusing on optical signal processing using nonlinear optical fibres. In particular, the position will focus on developing optical functionalities for energy-efficient optical communications, with a strong emphasis on implementing optical time lenses for advanced optical signal processing, such as time-to-frequency conversion (serial-to-parallel), spectral magnification using time lens based telescopic arrangements. The PhD candidate is expected to derive novel signal processing schemes based on time lenses, and study time lenses intensely, both theoretically and experimentally. The PhD student should derive fundamental limitations of time lens systems and derive requirements to nonlinear optical media used for making time lenses. A special focus will be given to explore novel highly nonlinear fibres, such as SPINE-HNLF from project partner OFS Denmark Aps, and arrive at guidelines for fibre parameters such as dispersion profile and threshold for SBS. Experimental demonstrations of high conversion efficiency and large bandwidth will be key goals. The PhD student will have a supervisor team from DTU Fotonik and from OFS Denmark Aps.

Candidates should have a master’s degree in engineering or a similar degree with an academic level equivalent to the master’s degree in engineering.

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.

The assessment of the applicants will be made by Professor (MSO) Leif K. Oxenløwe, Dr. Michael Galili and Dr. Lars Grüner-Nielsen, as well as the PhD school at DTU Fotonik.

We offer
We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.

The work will take place at DTU Fotonik and occasionally at OFS Denmark Aps.

Further information
Further information may be obtained from Head of Department Lars-Ulrik Aaen Andersen, tel.: +45 4525 3816.
