PhD-position in Photonics at Delft University of Technology: Photonic Components for a Photoacoustic Imaging Chip

Department/faculty: Applied Sciences 
Level: Master degree
Working hours: 38 hours per week 
Contract: 4 years
Salary: €2083 to €2664

Applied Sciences

The Faculty of Applied Sciences is the largest faculty of TU Delft, with around 550 scientists, a support staff of 250 and 1,800 students. The faculty conducts fundamental, application-oriented research and offers scientific education at the bachelor, master and doctoral levels. The faculty is active in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Applied Physics.

The Department of Imaging Physics of the Faculty of Applied Sciences performs cutting-edge research and education in imaging science to advance the fundamental understanding of physical phenomena leading to new innovative imaging principles and revolutionary imaging instruments. The groups of the Department focus on the topics biomedical technology, nanofabrication and nanoscopy, and wave technology.

Job description

Photoacoustic imaging is a medical diagnostic technique based on absorption of pulsed light by tissue. The absorption results in rapid thermal expansion of the tissue and generation of MHz frequency acoustic waves, which can be used to construct an image of the tissue. The great advantage of photoacoustic imaging as compared to regular ultrasound imaging is its chemical specificity, which results from structure in the absorption spectrum of the tissue. In this project you will design, fabricate and experimentally study silicon-based photonic components for photoacoustic imaging of human arteries. In particular, you will develop grating radiators and ring resonators as all-photonic components for a future photoacoustic imaging chip. The grating radiators are surface emitting devices capable of sending a beamlet towards tissue to be imaged. The ring resonators are pressure sensors, which respond to the acoustic waves with a strain-induced resonance shift. This project is a collaboration between the Quantitative Imaging, Optics and Acoustic Wavefield Imaging groups of the Department of Imaging Physics. The project further includes a medical centre and companies active in photonics as project partners.


You have a recently completed Master degree in Experimental Physics, Materials Science or Physical Chemistry, preferably in the field of (integrated) photonics or the properties of thin films.

Conditions of employment

TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home (with a contract of two years or longer), and the option of assembling a customised compensation and benefits package. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.

As a PhD candidate you will be enrolled in the TU Delft Graduate School. TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.
