Postdoc Researcher on Photonic Integrated Circuits for Lidar Sensors

Eindhoven University of Technology, Netherlands has an opening postdoc position in semiconductors. Successful candidate will have funding to work and study for 3 years in Netherlands. Applications will be evaluated immediately.

Photonics is widely regarded as the key enabling technology of the 21st century and its application and use 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.

A diversity of PIC-based sensors have been proposed in the last years, such as environmental sensors (e.g. gas sensing), medical sensors (e.g. optical coherence tomography) and fiber Bragg grating sensors for temperature or strain measurement. In recent years, the fast developments in the automotive industry towards self-driving cars have motivated a strong interest on light detection and ranging (LiDAR), which is the cornerstone technology for monitoring moving objects with high spatial resolution.

A fully solid-state PIC solution will not be sensitive to vibrations and will offer a series of additional advantages over mechanical-based LiDAR concepts, such as miniaturization, potential low-cost (it can be manufactured in large volumes in semiconductor fabs), high scanning speeds (it relies on photonic circuits used for Gigabit Internet data transmission), and flexibility for adaptive scanning (since the beam forming can be done on-chip).

Job description

At the TU-Eindhoven we have one of the world's best equipped cleanroom laboratories for research on photonic integrated circuits. We have demonstrated advanced Photonic IC's, integrating lasers, optical amplifiers, modulators and detectors with a variety of passive components in a single chips with dimensions of a few millimeters. See . The main application areas, so far, are in telecommunications and data communications, sensors and health. The new project envisages development of two fully integrated LiDAR systems one with a medium integration scale for use in avionics (helicopter landing system) and one with a high integration scale for use in self-driving cars. We have one open position in a large EU-funded project, called NewControl, coordinated by Infineon and executed in cooperation with a large number of European partners. In this project, TUe has a central role for the development of InP-based LiDAR transmitters based on optical phased arrays.

The position will focus on PICs with an ultra-high density of components targeting automotive applications. The research includes modification of the fabrication process for a higher integration density, device-level simulations (optical, electrical, thermal), device and circuit layout, process flow design, and device fabrication in the Nanolab@TUe cleanroom. The hired PosDoc will collaborate closely with other team members appointed in the same project.

We are searching for candidates with a background in photonic integration and with good team-work capabilities. Successful candidates should have good writing and documentation skills, excellent analytical and research capabilities and good communication skills. They must be able to organize their own work well and set and pursue their goals independently, while maintaining a high degree of collaboration with the team.

The candidate will collaborate with the NewCONTROL consortium, which includes experts on fabrication technology, electronic and photonic circuit design, photonic-electronic assembly, freeform optics, system-level LiDAR architectures, etc.

We are looking for candidates with PhD in Electrical Engineering, Physics or Applied Physics. The candidates should have a background in semiconductor devices (preferably semiconductor optical amplifiers, phase modulators) and general knowledge about semiconductor physics, modelling and component design. Experience with on-chip beam steering is a plus. Experience with design and characterization of PICs, and/or cleanroom fabrication of III-V devices is of advantage.

We offer a challenging job in an ambitious research group through a fixed-term appointment for a period of 3 years. As an employee of the university you will receive a competitive salary as well as excellent employment conditions. The gross salary for a post-doc researcher lies between 3.255 and 4.274, depending on experience and knowledge.

Moreover, an 8% holiday allowance and 8.3% end-of-year allowance is provided annually. Assistance for finding accommodation is available. The university offers an attractive package of fringe benefits such as excellent technical infrastructure, child care, savings schemes, and excellent sports facilities. Depending on the type of appointment, TU/e also provides opportunities for personal development by offering short courses in the PROOF program complementary to scientific skills.

For more information about the project please contact dr. Victor Calzadilla (V.Calzadilla[at] or prof. Meint Smit (M.K.Smit[at] ).

For information concerning employment conditions you can contact drs. Tanja van Waterschoot (T.A.M.v.Waterschoot[at]

If you are interested, please use ‘apply now’-button at the top of this page.

Candidates will be selected based on their graduation project, relevant experience and skills, writing skills and publications, work experience and interviews. Typical recruitment procedure will involve a skype meeting, followed by a face to face interview with a presentation to the group in the second stage.

Please bear in mind: you can only upload 5 PDF documents (up to 10MB each).
