Are you a highly-motivated physicist with a strong interest in nanotechnology and optoelectronic experiments? The 2D Nanophotonics group
within the Institute of Physics is seeking an excellent and ambitious PhD candidate to perform fundamental research at the interface of nanophotonics and two-dimensional (2D) quantum materials for the project "Tunable metasurfaces for analog image processing
Optical image processing is at the heart of many new technologies, including augmented reality, autonomous driving, and optical eye tracking. It is usually performed by digital processing of images that are captured by a digital camera, and is thus very energy-intensive and limited in speed. Recently, it has been demonstrated that optical metasurfaces - 2D geometries composed of nanoscale light scatterers - can be designed to perform mathematical operations on optical images directly in the analog optical domain, without the need for electronic processing. This enables highly parallelized image processing at the speed of light, where the mathematical operation is defined by the nanoscale geometry of the sample.In this project, you will combine dielectric metasurfaces with exciton resonances in 2D quantum materials to develop the next generation of tunable metasurfaces that can actively switch their mathematical operation.
With these nanoscale devices, you will study what range of mathematical operations can be performed, characterize the fundamental limits of minimal energy consumption, and explore the integration of these computing metasurface directly onto a CMOS camera.
You will be joining an exciting team of researchers with a strong emphasis on collaboration.What are you going to do?
You will perform fundamental research on the understanding, control, and use of monolayer 2D van der Waals materials in nanophotonic metasurfaces with an electrically-controllable optical function.
- fabricate optical metasurfaces and nanoscale devices in the cleanroom of the AMOLF NanoLab Amsterdam (https://amolf.nl/nanolab);
- design and perform high-sensitivity optical and electronic experiments;
- develop theory and computer simulations to support the experiments;
- present your results in international workshops and conferences;
- collaborate with other members of the research group, other groups within the Quantum Materials cluster, AMOLF, and (international) collaborators;
- take part in the teaching efforts of the group, including supervision of bachelor and master students.
