Doctoral Candidate: Robert Petersen


Host institution: Technical University of Denmark (DTU)

Project: Fabrication, simulation and characterization of few-mode, rare-earth-doped amplifier fibres and other specialty fibres


Robert Petersen obtained his Bachelor of Science in Physics from the University of Kiel, Germany. For his bachelor’s thesis, he performed optical diagnostics on a novel plasma source. He then went on to pursue a Master of Science in Photonics at Lund University, Sweden. During his master’s degree project at the Lund high-power laser facility, he worked with a terawatt laser and used spatial light modulation and a phase retrieval algorithm to optimize the focal spot of an infrared laser beam.

Project Objectives:

  • Managing and limiting detrimental mechanisms due to HOMs in specialty fibres;
  • Fibres supporting HOMs to project partners.

Expected Results: 1.Improved fibre designs for suppression of HOM propagation. 2.Setups for characterization of HOMs. 3.Improved understanding and simulations of detrimental effects of HOMs in rare earth doped fibre amplifiers.
