Photonic chips can play be a crucial role in applications such as autonomous driving or medical imaging due to their capacity for extremely fast and energy-efficient data transmission. However, their adoption is currently held back by the considerable cost involved in the production of these devices. Ph.D. candidate Matthijs van Gastel has developed new ways of assembling photonic devices using glue, which is accurate at the sub-micrometer scale. The researcher at the Control Systems Technology group in the department of Mechanical Engineering defended his thesis on 25 March.
