Quantum photonics provides a promising route towards quantum communication, computing, and simulation. In our group, we develop quantum photonic building blocks and combine them into large-scale systems. There are several thesis opportunities in topics such as:

• Large-scale photonics: You will design and test reconfigurable integrated photonics based on MEMS tailored to cryogenic operation at color center wavelengths [1].
• Hybrid integration: Combining quantum photonic building blocks into a scalable system requires the integration of different materials [2]. You will develop efficient hybrid integration methods and build a library of high-quality materials and devices such as color center chiplets in diamond and silicon and single-photon detectors.
• Qubits in silicon: You will theoretically study the effects of strain and charges on the atomic scale and fabricate and characterize color center qubits, integrated photonic waveguides, and MEMS in silicon using free-space and integrated optical spectroscopy techniques [3].

Student profile: Independent, curious and creative, comfortable with experiments, hard-working.

Background: applied physics, electrical and mechanical engineering, computer science, optics.

Master thesis opportunity on photonic MEMS in collaboration with IMEC

We are searching for a student to start as soon as possible with a masters thesis. We will be interviewing candidates in a rolling basis.

Topic: Design of integrated photonic MEMS for quantum information processing in a new optimized large-scale platform from IMEC. The work will combine photonic integrated circuits, mechanics, and electrostatics into micro- and nano-scale complex devices for the reconfiguration of optical paths carrying photonic flying qubits. This is a great opportunity to help shape a new technology with huge potential for classical and quantum computing, sensing, and communications.
