Ge-on-silicon waveguide circuits for spectroscopic water quality control 

Imec

Imec is the world-leading research and innovation hub in nanoelectronics and digital technologies. The combination of our widely acclaimed leadership in microchip technology and profound software and ICT expertise is what makes us unique. By leveraging our world-class infrastructure and local and global ecosystem of partners across a multitude of industries, we create groundbreaking innovation in application domains such as healthcare, smart cities and mobility, logistics and manufacturing, and energy.

As a trusted partner for companies, start-ups and universities we bring together close to 3,500 brilliant minds from over 70 nationalities. Imec is headquartered in Leuven, Belgium and also has distributed R&D groups at a number of Flemish universities, in the Netherlands, Taiwan, USA, China, and offices in India and Japan. All of these particular traits make imec to be a top-class employer. To strengthen this position as a leading player in our field, we are looking for those passionate talents that make the difference! Currently we are looking for a motivated Postdoctoral Researcher.

The job

The Photonics Research Group (about 85 people) is associated with IMEC, and is part of the Department of Information Technology of Ghent University. The group is headed by Prof. R. Baets and has been active in photonics device research for many years. The other professors in the group are P. Bienstman, W. Bogaerts, B. Kuyken, N. Le Thomas, G. Morthier, G. Roelkens and D. Van Thourhout. The main research directions are silicon nanophotonics, heterogeneous integration, optical communication, photonic (bio)sensors and photonic integrated circuits for biomedical applications in the near-infrared and mid-infrared wavelength range. More in particular, the silicon nanophotonics work focuses on the design and fabrication of SOI-based photonic devices using standard lithographic techniques compatible with CMOS-processing.

The Photonics Research Group has been coordinating the network of excellence ePIXnet and is involved in a number of EU-projects, including the FP7 projects ActPhast, PLAT4M, Cando, and Pocket and the H2020 projects TOPHIT, TeraBoard, Aquarius, PIX4Life, MIRPHAB and Phresco. Furthermore, the group is partner of the Center for Nano- and Biophotonics of Ghent University and the group has been awarded three ERC Independent Researcher Starting Grants and one ERC Advanced Investigator Grant.

This Postdoctoral researcher will do research on silicon photonic integrated circuits for the spectroscopic analysis of drinking water. The project aims at realizing a germanium-on-silicon waveguide circuit that interfaces with a MidIR tunable laser and photodetector and that interacts with a water stream on top of the waveguide. The goal is to spectroscopically analyze the water sample and detect the presence of contaminants. In order to increase the sensitivity of the system, the use of coatings on the waveguides that gather the contaminants will be studied.

This work will be carried out in the context of the Horizon2020 “AQUARIUS” European project. Therefore, close interaction with other partners in the project will be required: i.e. the partners that realize the tunable laser source, the photodetectors, the coatings and the end-users of the system.

We offer you the opportunity to perform cutting-edge research in a challenging, motivating environment, working within a multidisciplinary team consisting of both photonic integration, sensing and electronics experts. A willingness to tackle challenges coming from these multi-disciplinary collaborations is a must.

You

We are looking for a highly motivated PhD candidate or post-doc with a background in photonics and/or sensing with an interest to do research on silicon photonic integrated circuits for the spectroscopic analysis of drinking water. You have good communication and interpersonal skills. You are proficient in English language skills to work in imec’s international working environment.

We

In exchange for your talent, passion and expertise, you will join a multicultural and high-tech company, with challenges there for the taking. Our flexible, progressive and informal working environment offers you a range of possibilities to take initiative and show responsibility. This is your opportunity to contribute to the technology that will determine the society of tomorrow. imec supports and guides you in this process; not only with words but with concrete actions. Through imecAcademy, 'our corporate university', we are actively investing in the further development of all our employees to assure their technical and personal growth. Your valuable contribution and that of your colleagues make imec a top player in its field. Your energy and commitment are therefore appreciated by means of an attractive and competitive salary with many fringe benefits.

We offer you a postdoctoral position of 1 year in the Photonics Research Group, imec’s associated lab at Ghent University. Apply online at www.imec.be/jobs including your cv, publication list and contact details of at least one referee.
