Development of optical components for
silicon-carbide quantum interfaces

The Quantum Materials group at LIST has recently built a new high-throughput quantum characterisation setup.

We have demonstrated that dozens of silicon carbide colour centres can be laser-excited and investigated at the same time. This gives us the edge in high-throughput quantum screening for ideal fabrication methods of nanostructures around these colour centres.

We are looking for an internship student in one out of two topics:

• Setting up a spatial light modulator to convert a Gaussian laser beam into dozens of individual laser beams. This will help us to achieve a much-improved signal-to-noise in our characterisation setup, which will further expand our lead.
• Setting up an electro-optical feedback-loop for an electro-optical modulator, to be able to carve out sub-nanosecond pulses from continuous-wave lasers. Depending on the results, this can also be extended to setting up a Fabry-Pérot frequency filtering cavity. Both techniques will be critical for our upcoming spin-photon entanglement experiments.

In this internship you will be able to work with state-of-the-art quantum optics equipment. You will be guided by experienced researchers in building electro-optics components.

We are looking for a candidate, holding a BSc degree, and able to demonstrate prior experience in experimental physics or optics, e.g., covering lab course experiments or other internships. An additional plus would be previous experience in hardware programming using Python.

Additionally, LISTs regulations require that the successful applicant is registered as a student at a university during the internship. The successful candidate must also be able to clearly communicate in English.

LIST offers:

• A thriving interdisciplinary and highly international environment.
• Working at the scientific forefront with colour centres in silicon carbide.
• Potential to make a significant contribution to current scientific challenges.
• Salary: 1000€/month.
