TNO Optics designs and develops high-end optical systems for a wide range of applications, including atmospheric monitoring from space, optical satellite communications, medical instrumentation, quantum technologies, structural health monitoring, and instrumentation for the semiconductor industry. We carry out this work for clients such as Airbus, NASA, and ESA, and for projects including the Sentinel-5 satellite for global air-quality monitoring and ITER.
Our expertise in optical technologies ranges from large-scale geometric optics to fiber optics, integrated photonics, and subwavelength metamaterials.
With a background in applied physics or engineering and a strong interest in integrated photonics, you will work as an Optical Scientist specializing in Photonic Integrated Circuits (PICs). TNO develops PICs for applications in opto-acoustics, quantum technologies, metrology, lidar, and biosensing. Our projects are typically multidisciplinary, combining PIC expertise with substantial knowledge of the relevant application domains.
You will work closely with your direct colleagues within the Optics group, with other TNO experts from different domains, and with external stakeholders, suppliers, and customers. In addition, you will collaborate with colleagues from the Holst Centre in Eindhoven and the Chip Integration Technology Centre in Nijmegen on hybrid integration and packaging processes.

As an Optical Scientist specialised in integrated photonics, you will be involved in the development, validation and implementation of PIC devices, and systems including PIC components, for various markets, including medical instrumentation, opto-acoustics, optical (satellite) communication and quantum technologies. Your work relates not only to optical aspects but also to thermal, mechanical and acoustic considerations. You will reflect on manufacturability, cost and optical and electrical interconnect, and analyse power budget, transfer functions and noise performance. You will contribute to the technology strategy, system architectures, chip designs and coordination of fabrication at selected foundries, as well as to experimental characterization and validation of PIC-based devices and systems. You will regularly and intensively discuss results, progress, deviations and possible improvements with teams of other technical specialists, project leaders and system engineers, based both at TNO and at our customers and partners. As an optical scientist you will be responsible for:
- Providing and maintaining up-to-date technical expertise on PIC technology
- Contributing to developing the vision and roadmaps for PIC technology at TNO and within our collaborations
- Developing and executing measurement protocols for standardized and custom tests and developing the required measurement setups
- Relating PIC performance to the higher-level architecture of the system in which the PIC is one of the components
- Successful validation of PIC technology in use cases for a range of applications
- Establishing collaborations and creating opportunities, including initiation of national and EU funded projects and programs
- Guiding colleagues from various departments, with a range of different expertise, to enable PIC-based systems
- Delivering high-quality work to satisfy the needs of our customers
A considerable level of creativity, autonomy and initiative is expected from you. To be able to perform your role well, it is important that you recognize yourself in the following profile:
- A PhD degree in physics or engineering, with knowledge relevant for the tasks described above
- At least 5 years of experience working in the domain of photonics, including fiber optics, PICs, and micro- and nanophotonics
- Experience in PIC modelling and device design (i.e. Lumerical, Photon Design, Synopsis, KLayout and Nazca or similar)
- Experience in the use of MATLAB and/or Python for modelling and signal processing.
- Knowledge of PIC material platforms, fabrication methods and technologies
- Experience in PIC chip-level testing
- A multi-disciplinary spirit, and the ability to connect multiple domains in physics to create integrated solutions
- You are ambitious and would like to further develop your skills in the field of integrated photonics with a focus on application-driven technology development
- Like to work together with others to achieve the best results
- Able to communicate fluently in English (you will have many international colleagues and collaborators)
