Scientific Internship: Partially-coherent Fourier interferometry for optical nanometrology

Date posted March 12, 2019
Type Scientific Internships

Fourier or k-space imaging is a fast and precise optical technique, which is widely used for characterization of sub-wavelength objects in science and in industry. It allows for single-shot, angle-resolved far-field measurements without the need of mechanical scanning.

Previously, our group has implemented a Fourier imaging setup with polarization and phase sensitivity. A further step to improve this setup is to include a spectrally tuneable, partially-coherent light source, which will require a modification of the current setup. The significance of measuring these additional properties of light (polarization, phase, wavelength) will be evident in improved accuracy, as well as reduced ambiguity when characterizing the properties of nano-objects in the far-field.

After completing this setup the student will be able to characterize nano-structures and perform comparisons to simulated results. Altogether, this will allow the student to predict extremely fine details about nano-object under investigation. Overall, the project is aimed at researching the benefits and accuracy limits of this technique, in view of current optical nanometrology challenges. To achieve this the student will be introduced to optical setup handling, electromagnetic simulations and cleanroom fabrication techniques.

About the group

The Resonant Nanophotonics group, led by Prof. dr. Femius Koenderink is 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. The Center for Nanophotonics provides a broad training through interaction with all the AMOLF groups in nanophotovoltaics and nanophotonics. During the project you will work with state of the art optical equipement and the Amsterdam Nanolab cleanroom facilty.

Qualifications

You have a Bachelors degree in physics, and participate in a Master study in physics. The internship must be a mandatory part of your curriculum. You have a nationality of an EU-member state and/or you are a student at a Netherlands University. You must be available for at least 6 months.

Terms of employment

At the start of the traineeship your trainee plan will be set out, in consultation with your AMOLF supervisor.
