PhD scholarship in Supercontinuum Laser Spectroscopy focused on spectroscopic techniques combined with broadband supercontinuum lasers

If you have a passion for experimental laser physics and would like to pursue a career within advanced spectroscopic techniques for chemical and gas detection, then this is the ideal opportunity for you!

This PhD scholarship in Supercontinuum Laser Spectroscopy will allow you to develop your skills as an independent scientist, working in a state-of-the-art photonics laboratory and combining exploratory research with a possibility for collaboration with both industry and academic partners.

Your PhD project will be focused on investigating different spectroscopic techniques and combine them with broadband supercontinuum lasers to achieve sensitive and specific detection of a broad range of molecules. These techniques include: attenuated total reflectance (ATR), fiber evanescent wave spectroscopy (FEWS), and multi-pass cell (MPC) gas spectroscopy. The goal of the project is to demonstrate new applications, such as in situ soil analysis and monitoring of environmental pollutants in water and air.  

You will work alongside a team of colleagues that are currently developing the next generation of supercontinuum lasers at the Fiber Sensors & Supercontinuum group, Department of Electrical and Photonics Engineering (DTU Electro), Technical University of Denmark (DTU). The group is headed by Prof. Ole Bang, and your main supervisor will be researcher Dr. Christian Rosenberg Petersen.

Responsibilities and qualifications
Your primary responsibility will be to build a spectroscopic detection system to detect molecular vibrational absorption in the mid-infrared (2-10 μm, 5000-1000 cm-1).

Your primary tasks will be to:

  • Design and build up an absorption spectroscopic detection system that is compatible with various different sample techniques (ATR, FEWS, multi-pass gas cell).
  • Perform absorption spectroscopy experiments using a mid-infrared supercontinuum laser on various samples to verify and calibrate the setup.
  • Investigate different sample types (solid, liquid, gas) and complexities that mimic real-life applications, e.g. soil analysis.

You should have experience working with:

  • Optics
  • Lasers

Other useful experience includes:

  • Spectroscopy
  • Spectral data analysis
  • Fiber-optics

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.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU’s rules for the PhD education.

The application will be assessed by Researcher Christian Rosenberg Petersen and Professor Ole Bang.
