About the research project
The ERC Advanced Grant project ProSync aims to bridge the performance gap between integrated microcombs and state-of-the-art laser frequency combs. By combining ultralow-loss silicon nitride photonics, heterogeneous integration, and advanced system-level experiments, the project will develop scalable microcomb technologies for optical communications, synchronization, and precision metrology.
We are recruiting for two postdoctoral positions with complementary research profiles:
- Microcombs for high-speed optical communications: This position will develop microcomb-based multiwavelength sources for high-capacity transmission and investigate their integration with silicon-photonic transmitter and receiver devices. The research will include coherent wavelength-division multiplexing, optoelectronic synchronization, and high-speed transceiver experiments.
- Microcombs for optical clocks and precision metrology: This position will develop octave-spanning, self-referenced microcombs that connect ultrastable optical references to microwave frequencies. The research will address optical-frequency division, frequency-comb stabilization, phase and timing noise, and metrological characterization, laying the foundation for integrated optical-clock and precision-timing technologies.
Who we are looking for
The following requirements are mandatory:
- A doctoral degree in Physics, Electrical Engineering, Photonics, or a closely related field, or an equivalent foreign degree. This eligibility requirement must be met no later than the time the employment decision is made.
- Documented experimental research experience in at least one of the two research profiles:
- fiber-optic communication systems, such as coherent optical communications, high-speed transceivers, or digital signal processing; or
- precision metrology and ultrafast optics, such as laser-frequency stabilization, optical frequency combs, optical-frequency division, or optical clocks.
- A strong research record demonstrated through peer-reviewed scientific publications.
- Demonstrated ability to plan, conduct, and analyse experimental research with a high degree of independence.
- Strong written and verbal communication skills in English.
- Demonstrated ability to collaborate effectively in an international and interdisciplinary research environment.
