In the Nanophotonics Section at DTU Fotonik, we perform fundamental experimental and theoretical research on the physics of light-matter interaction and explore possibilities for realizing new and improved photonic devices. Important areas of applications include quantum technology, integrated photonics, and devices that reduce global energy consumption.

Project description
The Casimir force is a dispersion force arising from quantum fluctuations in the electromagnetic vacuum. While often considered elusive, the Casimir effect can be very significant at the nanoscale but many aspects remain poorly understood or even unexplored. This PhD-project concerns the theory, nanofabrication, and characterization of novel nanomechanical devices. The two main goals of the project are first to measure the Casimir force in the <100 nm regime, where experiments so far very scarce, and second to employ Casimir forces to realize new functionalities in chip-scale photonics. As PhD-student in this project, you will investigate and explore these effects based on the silicon nanomembrane technology developed at DTU.

We seek an ambitious and motivated PhD student with a very strong experimental and/or theoretical background, who is interested in joining the active research team on nanoelectromechanical photonics and photonic nanophysics at DTU Fotonik. In the application, you should clearly state your motivation and scientific interests.

Candidates should have a two-year master's degree in engineering/physics (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. Experience in the following elements of our research will be an advantage:  

  • Semiconductor nanotechnology and silicon photonics.
  • Finite-element modelling.
  • Analytical modelling within multiple areas of physics including mechanics and electrostatics.
  • Quantum electrodynamics.
  • Cleanroom work.
  • Optical and electrical measurement methods.
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 the DTU PhD Guide

The assessment of the applicants will be made by a Department panel.
