PhD Researcher in Advanced Fiber Lasers and Supercontinuum Technology

1 month ago


Kongens Lyngby, Lyngby-Tårbæk Kommune, Denmark Danmarks Tekniske Universitet (DTU) Full time

Join us in our pursuit of scientific excellence as we develop innovative fiber laser and supercontinuum source technologies. Our team is working on groundbreaking projects that push the boundaries of ultrafast fiber optics and spectroscopy.

About the project

We are developing four new all-fiber supercontinuum sources, or beamlines, to cover an enormous bandwidth. The UV beamline 1 will utilize gas-filled hollow-core silica fibers and meta-surfaces, covering 33-1100 nm. The near-IR beamline 2 will employ solid-core silica photonic crystal fibers, covering 400-2400 nm, and will use all-normal dispersion (ANDi) fibers pumped with femtosecond lasers to achieve record-low noise for spectroscopy and Optical Coherence Tomography (OCT) imaging applications. The low-noise beamline 3 will also use commercial fluoride fiber to cover 1-5 μm. Beamline 4 will push the record IR edge in all-fiber mid-IR supercontinuum sources to 15 μm using chalcogenide soft-glass fibers.

Your responsibilities

As a PhD researcher, you will focus on the development of beamlines 2-3, using coherent ANDi supercontinuum generation pumped with ultra-short femtosecond fiber lasers. You will be in charge of developing both the femtosecond pump lasers and the supercontinuum sources. You will work as part of the team implementing these sources in our in-house developed spectroscopy and OCT systems for cutting-edge applications within imaging and trace gas detection.

Qualifications and requirements

We require you to have experimental qualifications within fiber optics and fiber lasers and to document a drive to build things yourself. You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Assessment and appointment

The assessment of the applicant will be made by Professor Ole Bang and by the DTU PhD Council. The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations.
