Job description

Photonics is widely regarded as the key enabling technology of the 21st century and its applications in many scientific and industrial fields is accelerated though Photonic Integrated Circuits (PICs), which combine many optical components into a miniaturized chip format. Similar to electronic ICs, PICs are revolutionizing areas such as healthcare, communication and sensing and have the potential to be disruptive to the whole society.

We are currently building core competences for the establishment of the Photonic Integration Technology Center (PITC). The goal of PITC is to advance photonic integration technology towards industrial use. We work together with Europe's main players in the photonics industry to coordinate access to this technology, enhance existing photonic platforms and provide research and development services for companies. The technology center will work to further mature promising research results by lifting them to higher technology readiness levels (TRL), thus bridging the gap between excellent scientific output and its industrial exploitation. 

The position is funded by the OIP4NWE project (, whose aim is to establish infrastructure and technical capabilities for the development of photonic integrated circuits (PICs) in an open innovation environment. In the framework of this project, a new fully automated 4” MOVPE reactor for InP will be installed in the NanoLab@TU/e cleanroom in cooperation with AIXTRON GmbH. This state of the art tool will contribute to lifting the TRL of PICs through a better control of layer thicknesses, doping levels, material composition and contamination control. After being optimized to produce high quality epitaxy wafers, a process flow will be developed to integrate them with lithography projection tools.

We are currently also upgrading other key cleanroom tools (Inductively-Coupled Plasma Reactive-Ion Etching, and Plasma-Enhanced Chemical Vapor Deposition) with automatic cassette loading for high process repeatability and robustness. We have the vision to further extend our manufacturing capabilities over the next years to create a best-in-class InP PIC pilot line infrastructure, which can be the cornerstone for joint technology developments in an open innovation setting.

Job requirements

We are looking for candidates with studies on microelectronics, physics/photonics or microfabrication technology with a strong background in semiconductors. Regarding the education level, we are flexible to interview candidates with HBO, MSc or PhD, as long as the candidate shows a solid background and relevant expertise. The scope of the position may be slightly adjusted in accordance with the ambitions of the successful candidate. The candidate should have strong affinity with hands-on experimental work. Experience with cleanroom work is required, and experience in epitaxial growth of layerstacks for photonics is highly desired. Chemistry knowledge is an advantage. She/he should also have an inquisitive character and be prepared to expand her/his knowledge. The candidate should have a solution-oriented mentality as well as good command of English language.

You will be expected to:

- Carry out process development within the framework of current projects like OIP4NWE. In the short term, the work will be highly focused on epitaxial growth and analysis of thin film stacks; in the mid-term you will be trained to be able to carry out wafer processing beyond epitaxy, including fabrication of photonic integrated circuits (lithography, etching and thin-layers deposition, etc.).

- Be responsible for the MOVPE tool including calibration and growth and evaluation of layerstacks, maintenance and safety.

- Contribute in the process of designing layerstacks for photonic devices (e.g. lasers, amplifiers, modulators).

- Work and communicate efficiently in a team environment and proactively contribute with your own ideas and solutions.

- Report and document technical progress.

- Maintain fabrication processes.

Conditions of employment

We offer

We offer a challenging job within a dynamic setting, where you can develop further your technical skills. We offer a unique mix between academic and industrial environment due to our close collaboration with research groups at the university and also our industrial partners. You will join a team of young and open-minded experts that have the aim of making photonic integrated circuits a mainstream technology.

Conditions of employment

We offer a fixed-term position for 2-year; after this, possibilities for extension or permanent contract will be evaluated. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, including:

  • A starting gross monthly salary between € 2,790 and € 4,402 scale 10.
  • Additionally, 8% holiday and 8.3% end-of-year annual supplements.
  • Additional benefits, including excellent technical infrastructure, child care, holiday savings schemes, and sports facilities.
  • Assistance for finding accommodation can be offered for foreigners

The University supports the employees with diverse courses for professional development.
