Internship

We are currently looking for an intern to work on a nanofabrication project in our Quantum Dots research group. The applicant ideally would have a basic experience, or willingness to learn nanofabrication tools like e-beam lithography and etching. The main goal of the project is to fabricate a phase mask by etching fused silica in various thicknesses to impart optical phase delay (specifically as linear 0-pi-0-pi- phase mask, with etch depth such that there is a pi phase for ~ 800 nm, see [1]. This phase mask would then be used to generate square-shaped laser pulses as part of our existing project investigating advanced excitation protocols for quantum dots [2,3].

The duration of the project would depend on the experience of the applicant, who would carry out this work at the Innsbruck Nanofabrication Facility (10-15h/week). 

Please approach Vikas.Remesh@uibk.ac.at for further information.

MSc theses

Good MSc students are always welcome to embark on one of our exciting Masters Thesis topics  and are encouraged to take courses 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 . If you are interested on one of our topics, please contact us, ideally at the end of the winter term.

externals: students from outside UIBK

We only consider EU-nationals or applicants with a valid work visa for Austria for any internship positions.

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.
