Postdoc in Microcombs

Information about the research and the division
An optical frequency comb is a laser source whose spectrum is made of evenly spaced and narrow frequency lines that maintain broadband phase coherence across the bandwidth. Microresonator frequency combs (microcombs) constitute an alternative platform to femtosecond mode-locked lasers for realizing frequency combs on a chip scale. Their compactness, compatibility with standard semiconductor fabrication techniques and large (> 10 GHz) line spacing enable new opportunities in frequency synthesis and metrology: from advanced communications to radio-frequency photonics.

In the past years, our group has demonstrated microcombs based on silicon nitride with outstanding performance in terms of conversion efficiency. We have shown the potential of these light sources in the context of coherent optical communications and explored nonlinear physics in an arrangement of linearly coupled cavities. We are looking for a postdoctoral fellow to join our team and investigate new research avenues based on this platform, comprising the exploration of different operational wavelengths for optical spectroscopy, the realization of phase-coherent light wave communications or the synthesis of high-frequency microwaves. The research project is funded by the European Research Council (ERC) and the Swedish Research Council (VR).

The Photonics laboratory at the Microtechnology and Nanoscience Department (MC2) is a dynamic and creative group with about 30 members working in an international and collaborative atmosphere. We perform both curiosity-driven and applied-research in the areas of optoelectronics, nano photonics, and fiber optic systems. We enjoy a state-of-the-art laboratory for microcomb research and have access to in-house cleanroom facilities to manufacture our own photonic devices based on silicon nitride.

Major responsibilities
As postdoctoral fellow, your main responsibilities are to lead and conduct research, and guide junior PhD students. You will have the freedom to contribute with your ideas and collaborate with other senior researchers and professors.

Qualifications
You should have a PhD degree (or equivalent) in Applied Physics, Engineering Physics, Electrical Engineering or similar. You must have experience with supervision of junior students (PhD or Master). You must have solid experience with laser frequency combs.

Knowledge of standard finite element solvers and computational techniques in nonlinear optics (generalized nonlinear Schrödinger equation, Lugiato-Lefever equation, etc.) is a plus.

Contract terms
The postdoctoral position is a full-time employment position limited to 2 years. We offer a competitive salary, excellent working conditions and access to world-class facilities and infrastructure. Starting date is negotiable.
