The research group of Associate Professor Søren Stobbe is a newly established research group at DTU Fotonik within the Quantum and Laser Photonics Group. Our research scope ranges from exploration of fundamental aspects of photonic topological insulators to application-oriented research within nano-optoelectromechanics. The main research methods are semiconductor nanofabrication, optical experiments, and theoretical modelling. It is our ambition to publish highlights of our results in top journals and to push the application-oriented research to real-world applications. Søren Stobbe has published numerous papers in Nature, Science, Reviews of Modern Physics, Physical Review Letters., etc., founded two companies, and holds several patents.

This PhD-project concerns the design, nanofabrication, and optical characterization of a novel type of spectrometer based on nanoelectromechanical photonics. Spectrometers are becoming increasingly important within telecommunication, optical interrogators, quantum technologies, healthcare, and much more. Currently available spectrometers are bulky and expensive and the development of compact spectrometers could have a very high commercial impact – and developing them requires interdisciplinary research within the physics and engineering of semiconductors, nanotechnology, nanophotonics, and nanomechanics.

Responsibilities and tasks
As PhD-student in this project you will investigate novel concepts within nanoelectromechanical devices, in particular developing a compact nanoelectromechanical spectrometer. Your main responsibilities will be: 

  • Concept development and numerical design.
  • Nanofabrication using silicon photonics technology at DTU Danchip, a large state-of-the-art cleanroom just a few steps from our optical labs.
  • Optical measurements and data analysis.
  • Exploring further concepts and applications based on nano-electromechanical systems, which may involve basic research within photonic topological insulators, quantum information processing, or applied research towards creating a spin-out company – depending on the research progress and interests of the candidate.
Your daily work will be in close collaboration with other team members including other PhDs and postdocs working on related projects. Our research environment is informal, creative, and ambitious.

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, with very good results (high GPA), possess strong analytical skills and keen interest in experimental work. Furthermore, a strong interest and background within one or more of the following fields will be an advantage:
  • Semiconductor nanofabrication.
  • Nanophotonics,
  • Numerical methods.
  • Nano/microelectromechanical systems 
Approval and Enrolment
The scholarship 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 Associate Professor Søren Stobbe and Professor Jesper Mørk.
