Development and testing of control electronics for laser stabilization and optical-to-microwave frequency conversion for use in a compact optical clock
Optical clocks represent the frontier of precision timekeeping. To reach unprecedented levels of accuracy, ultra-stable laser systems locked to atomic or molecular references are essential. In this internship, you will work on developing and characterizing control electronics for laser stabilization and optical-to-microwave frequency conversion for use in a compact optical-clock prototype.
Specific tasks and goals include:
- Develop modular control electronics for the laser frequency locking, optical-to-microwave frequency conversion, and temperature stabilization of various components.
- Build first prototypes and carry out their testing and performance analysis.
- Collaborate with a team of experts in photonics and frequency metrology.
- Contribute to the broader goal of developing fundamental components for high-performance optical clocks.
The internship will be conducted at the Saxion research group Applied Nanotechnology and the Talent and Learning Center for Quantum, Photonics, and Semicon (within the PhotonDelta national program), in collaboration with Prof. David Marpaung’s NLNP research group at the University of Twente and the startup Temporal. Besides exciting and challenging tasks, this internship allows getting familiar with the regional and national quantum and photonic ecosystems and offers many networking opportunities.
