Vacancy: Photonic Integrated Solid-State Lasers for Quantum Systems and Metrology (Open)

Context

Current photonic integrated laser systems, such as III-V laser diodes and Kerr frequency combs, have shown great promise to realize scalable quantum systems. However, the performance of these laser systems is still far from what is possible using tabletop free-space or fiber laser systems. During the ERC StG LASIQ we will research novel photonic thin-film materials to create beyond state-of-the-art on-chip laser systems. This work will build on the novel solid-state laser integration technologies and state-of-the-art micro transfer printing capabilities of the Photonic Research Group.

Job Description

For this project you will be working in a multidisciplinary photonic integration team led by Prof. Kasper Van Gasse within the Photonics Research Group of Ghent University and imec.

The estimated breakdown of the research activity is approximately 50% clean room work and process development, and 50% optical simulations (Lumerical, mode solvers, FDTD, inverse design, ...) and optical experiments. The focus will be on fabricating novel devices and measuring them in the state-of-the-art laser lab built in the framework of ERC StG LASIQ. The Photonics Research Group clean room has unique equipment for heterogeneous laser integration and micro-transfer printing.

You will be responsible for:
- Developing novel fabrication methods for solid laser waveguides (e-beam lithography / dry-etch optimization / thin-film development)
- Testing and characterizing on-chip solid-state lasers
- Modelling and design of PIC narrow linewidth CW lasers for trapped ion/cold atom/color center quantum control
- Modelling and design of PIC femtosecond lasers for frequency metrologyDescribe the range of tasks in a sufficiently specific way.

Candidate Profile

- You hold a thesis-based doctorate.
- We are looking for a highly motivated postdoc to develop novel on-chip laser systems that will enable scalable on-chip quantum and metrology systems.

About Us

The Photonics Research Group (about 100 people) is an associated lab of imec, and is part of the Department of Information Technology of Ghent University. The group is headed by Prof. D. Van Thourhout and has been active in photonics device research for many years. The other professors in the group are R. Baets, P. Bienstman, W. Bogaerts, S. Clemmen, A. Curto, C. Haffner, B. Kuyken, N. Le Thomas, G. Morthier, G. Roelkens, K. Van Gasse. The main research directions are silicon(-nitride) nanophotonics, heterogeneous integration, optical communication, quantum optics, photonic (bio)sensors and photonic integrated circuits for biomedical applications in the near-infrared and mid-infrared wavelength range. More in particular, the silicon(-nitride) nanophotonics work focuses on the design and fabrication of SOI-based photonic devices using standard lithographic techniques compatible with CMOS-processing. This happens in collaboration with imec.

The Photonics Research Group has been coordinating the network of excellence ePIXnet and is involved in several EU-projects, including Horizon Europe, CHIPS-JU, MCSA-ITN and Digital Europe projects.

Furthermore, the group is partner of the Center for Nano- and Biophotonics of Ghent University and of the UGent Core Facility NaMiFab.

The group has been awarded six European Research Council ERC Starting Grants, one ERC Consolidator Grant, two ERC Advanced Investigator Grants and is involved or leading 4 EIC Projects.

The groups leads ePIXfab, the European Silicon Photonics Alliance.
