Aim of the thesis / tasks

Recent years have seen increasing efforts in pushing the size of optoelectronic devices down to the micro- and nanoscale. Miniaturized photonic sensors are of particular interest because they can potentially be integrated in small, cheap and portable devices. The objective of this thesis is to characterize existing photonic sensors on chip and at a wafer level, with a special focus on integrated mid-IR light-sources. On the basis of the results, the successful candidate will have the chance to elaborate a design for a new generation of sensors with enhanced performance in the mid-IR spectral region.

In particular, the candidate will:

  • gain a fundamental understanding of both, the sensing principle and the critical parameters influencing the sensing properties of the current devices;
  • develop a testbench for characterization of integrated mid-IR light sources
  • experimentally characterize novel mid-IR integrated sensors based on the investigated sources and other photonic elements (e.g., waveguides or photonic crystals), and analyze measured data
  • apply the theoretical and experimental knowledge acquired during the first part of the thesis to elaborate new concepts for mid-IR sensors

Profile / Requirements

  • Master student in physics, photonics, microsystem technology or similar fields
  • Good teamwork skills, well organized work strategies
  • Hands-on experience in an optics lab.
  • Good communication skills in English and/or German.
  • Advanced MS office skills.
  • Experience with control-, evaluation- and visualization software (e.g. Matlab, Mathematica, Python,…) is beneficial.

Start Date / Duration / Contract

  • Start date (planned): March 2019
  • Duration (planned): 6 months
  • Contract: Payment is based on the collective contract.
  • Place: Villach
  • Suggestions with regards to the academic supervision are welcome.
