Postdoc position in Design and Characterization of Photonic Crystals under Different Surface Mechani | The Metamaterials group,DTU Photonics Engineering


Posted: 07-Feb-22

Location: Copenhagen, Denmark

Type: Contract

Required Education: Doctorate


Academia, Research Laboratory

Job Function:


Technical Division:

Nanophotonics (ON)

Photonic Detection (PD)

Photonic Metamaterials (OP)

Years of Experience:


The work within this project will be done in cooperation between the Metamaterials (DTU Photonics Engineering) and Nano Bio Integrated Systems (DTU Bioengineering) groups.

The Metamaterials group at DTU Photonics Engineering specializes in design, fabrication and characterization of optical metamaterials and nanostructures aiming effective control of light propagation and interaction with different materials in different frequency ranges. The Nano Bio Integrated Systems group at DTU Bioengineering (NaBIS) is an interdisciplinary group specializing in application-driven research within the fields of biotechnology and environmental monitoring. The vision of groups cooperation is to integrate micro- and nanoscience in lab-on-a-chip systems with the aim of developing novel technologies for sensing as well as biological and medical diagnosis.

We offer an 18-months postdoc position, within the multidisciplinary EU FET-project StretchBio. The StretchBio project is a collaborative project between several international partners, aiming on using optical tools to evaluate the presence of malicious cancer cells in tissues. To achieve this challenging objective, StretchBio investigates how the presence of mechanical stress on top of the nanopillars forming the photonic crystal matrix will perturb it’s optical performance. As most of the work is supposed to be done at DTU Photonics Engineering, the postdoc will be allocated with the Metamaterials group.

Responsibilities and tasks
This position will focus on elaborating a design for photonic crystals with high mechanical susceptibility and a principle for characterization mechanical superficial stress applied on the photonic crystal matrix, assembling and calibrating a setup for such characterization and performing measurements to test the feasibility of the setup.

Your main responsibilities will be

  • To propose and elaborate an effective optical principle of superficial localized stress characterization.
  • To develop a photonic crystal design that allows optical measurements of minute mechanical deformations
  • To implement a sensitive characterization setup to measure the changes in optical properties of a mechanically actuated photonic crystal.
  • To develop routines for effective and robust measurements of the applied stress.
  • To perform analysis of applicability of the routine and it’s critical parameters for different types of surface stress.


Candidates should have a PhD degree in the field of Photonics Engineering, Physics and Nanotechnologies, or equivalent.

The candidate should possess most of the following:

  • General knowledge in nanofabrication in clean room environment.
  • Advanced experimental experience in optical characterization of photonic crystals
  • Advanced knowledge in photonic crystal design
  • Knowledge of sophisticated photonic equipment
  • Ability to work independently, to plan and carry out complicated research tasks, and to be a part of a large research team.
  • Strong analytical skills and excellent judgment ability.
  • Team spirit and excellent collaboration skills
  • Computer proficiency.
  • Excellent communication skills, fluent written and oral English.

Flexibility and self-motivation are desired skills at DTU. In addition, we expect you to be interested in collaboration and take personal responsibility for your work.
