MSc theses

Good MSc students are always welcome to embark on one of our exciting Masters Thesis topics (German) and are encouraged to take the course component "704042 Forschungspraktikum experimentelle Quantenphysik" in our group to prepare them for the thesis research work. 

All master theses in our group are very close to the cutting-edge research in their respective fields and involve various experimental aspects where you are working with the most advanced devices and methods to solve current problems in the area of quantum photonics. Furthermore, you will learn about theoretical aspects of modelling quantum optical phenomena and of semiconductor physics. Altogether you will acquire an excellent basis for an industrial or academic career.

Foreign students beware that MSc students are not normally funded in Austria. Furthermore, please inform yourself about the necessary requirements and procedures for studying at the UIBK (read more).

BSc theses

We offer topics for Bachelor theses (German). If you are interested on one of our topics, please contact us, ideally at the end of the winter term. In general, a first organizational meeting of the course  "704710 Seminar mit Bachelorarbeit: Experimentalphysik" takes place in early February. 

Internships
internals: for students at UIBK

The experimental physics lab course “704727 PR Laborpraktikum der Experimentalphysik: Optik” is rated with 5 ECTS, which corresponds to approximately three weeks of fulltime work including the preparation of a lab report.  In any case, the lab part should be treated with higher priority. If you are interested, please register with sufficient lead time (typically 1 week before the start of a semester) and contact the supervisor of your choosing. The supervisor in the photonics group is Prof. Gregor Weihs.

externals: students from outside UIBK

Internships are only considered for EU-nationals or applicants with a valid work visa for Austria.

Hong-Ou-Mandel interference

If two indistinguishable photons impinge on a beam splitter simultaneously, they always leave the beam splitter together. This effect was first observed by Hong, Ou and Mandel  [Phys. Rev. Lett. 59, 2044 (1987)]. In the lab course your task will be to set up such a HOM experiment using the pair source from our experiment on the Bell inequality (FP2) and a fiber beam splitter, as well as to measure the HOM interference.

Open cavity to create exciton-polaritons in organic molecules

When a medium with an optical transition is placed in an optical cavity with high quality factor one can achieve strong coupling between the medium and the light field. In this regime we cannot treat the system simply by looking at the photons and excitations of the medium (e.g. excitons) individually, but rather have to treat them as new quasi particles – called polaritons. In the lab course your task will be to build and characterize such a cavity with mirrors of very high reflectivity.

Precision measurement of the nonlinearity of high-precision photodetectors

In our measurements testing the validity of Born’s rule in quantum physics [T. Kauten, et al., New J. Phys. 19, 033017 (2017).] we need extremely precise and linear, or in other words, extremely accurately characterized, detectors. In the lab course your task will be to measure and model the nonlinearity from a photo receiver using the beam combination method.

Stabilization of a triggered single photon source

Based on the creation of photon pairs through spontaneous parametric fluorescence, we can realize a single photon source through measurement of one of the photons. In the lab course your task will be to expand the existing source in such a way that the relative count of photons in the measurement arm stays constant, as accurately as possible, compared to the one in the trigger arm. In order to achieve that, you should couple the photon pairs into a fiber, separate them with a fiber beam splitter and use the trigger signal to stabilize the source on the one hand, and characterize stability on the other hand.
