Postdoc: Subwavelength imaging with reconfigurable metasurfaces

Optical microscopy is a superior method to image small structures with low noise and high throughput, but famously limited by the diffraction limit. Metasurfaces can structure optical near fields with subwavelength resolution. In this project, we aim to demonstrate novel methods towards efficient near-field image reconstruction from the complex scattering of metasurfaces. We seek to exploit the relation between near and far fields of metasurfaces to decode spatial information of nearby objects. Combining scanning probe techniques, active reconfiguration of optical fields, and advanced reconstruction algorithms such as compressive sensing, we aim to experimentally uncover the physical principles and demonstrate the potential of this technology. You will work in a small team to address these goals, and be involved in both the theoretical and experimental associated challenges.

About the group

The Resonant Nanophotonics and Photonic Forces groups, led by Prof. dr. Femius Koenderink and Prof. dr. Ewold Verhagen, respectively, are part of the Center for Nanophotonics at AMOLF. We investigate the fundamental physics of light-matter interactions at the nanoscale as well as the applications they allow. This project is performed jointly by the two groups, and carried out in close collaboration with the research partner TNO (Netherlands Organization for applied scientific research, based in Delft). You are expected to actively work together with researchers at TNO, and will be seconded on part-time basis to the TNO Optics Department to work with the TNO mechatronics and metasurfaces experts (contact Giampiero Gerini). The project involves the use and development of advanced optical measurement techniques and theoretical/analysis tools, with extensive support from the group leaders and AMOLF and TNO technical staff.


We seek an excellent candidate with a background in physics or electrical engineering who has a doctoral degree, or has met all the requirements and will receive the doctoral degree shortly. Candidates with relevant experience, preferably in optics/photonics and/or signal processing, are especially encouraged to apply.

Terms of employment

You will be offered an employment of 2 years in the service of NWO-I with excellent employment benefits. The position is intended as full-time (40 hours / week, 12 months / year).

AMOLF is a small-scale institute with different disciplines and is known for its unique collaborative culture. Your development will be stimulated in the form of training on the job together with relevant courses. We offer generous relocation expenses and support with finding housing and visa application. NWO-I also offers you facilities to combine work and private life, like partly paid parental leave. Curious about our other benefits? See the employment regulations of NWO-I.
